http://perlce.sf.net is a bit outdated with two ways: its wiki become read-only due to site reorganization, and there are no fresh builds there.

But things are not fully stagnated, because development branch of Perl receives updates WRT 'wince' from time to time. Also, mailing list there still used a bit, so there are people who try doing a builds from time to time.
I hope "perlce" mailing list will be created soon at perl.org

As for newer build - perl588 could be built with few modification to perl source tree (changes did not got through maintenance release), so better approach is to use 5.8.2 version, or build your own - this is all doable, see for example this message from perlce ML archive

In the current development branch there were some reorganizations, but mostly things are the same.
So may be even better bet could be to build current development snapshot, it should go more smoothly.

Still, you can try existing binaries, just check your processor with http://msdn.microsoft.com/embedded/usewinemb/ce/supproc/default.aspx, and get proper binaries.

I am planning uploading newer binaries to perlce.sf.net within approximately a month.
But there are no build of perl/Tk for perl-5.8+ releases, because porting this monster is a great amount of work. perl/tk is available for perl 5.6, and there's no Unicode there.
So only Tcl/Tk-8.4+ (which is freely usable from perl) is available for WinCE platform.

OK, sounds like I've got some work to do. Will your binaries run on Intel XScale CPUs ? (I'm hoping to get a Verizon VX6700)

FWIW: my need has nothing to do w/ building pTk, or GUIs of any type. My need is actually much simpler/utilitarian: I've built up a spam killer script over the years that does a pretty good job at killing most of the garbage (esp. the more dangerous variety). On my laptop/desktop, I run both that script and Thunderbird, so I'm pretty safe.

Alas, to the best of my knowledge, the only email client for WinMobile is LookOut!, so my paranoia level is pretty high, and makes running my spamkiller script pretty critical.

Update: found some other email clients, so now I've got even more work to do <sigh/>

I think this is not very realistic, due to OS limitations.
Perl build is based on CELIB, which also isn't very robust.
Mostly you'll be able to run toy scripts, but no daemons etc.

BTW Is your WinCE version free of Serious Design Limitations?

This is how development work - you want => you do => all use :)
The technology now works, but the more people will go the path - the wider path will be

Update: I also note that later versions of the PDA device you mention, the Sharp Zaurus, can be bought with embedix, an embedded linux variant, although there are clearly loads of choices out there and I'd look at http://uclinux.org/

Is there any specific reason why it has to be Windows ?

Like it or not, WinMobile has pretty much captured the PDA/SmartPhone market (at least in the US). I actually looked into the Nokia 9300 (running Symbian), but the US model has neither WiFi nor a camera. I occasionally hear of Linux phones, but they never seem to show up w/ any of the major carriers.

Having been an early adopter of the Z, and then getting burned by spotty support, and start/stop product releases, (not to mention extremely low battery life), I'm very reluctant to buck trends in that arena any more. I'm certainly not going to try to negotiate w/ my cell carrier to activate an unsupported phone. The Z was nice for loading up Perl and other *nix tools...but if I'm going to have to do self-support, I'd rather do it for Perl than every other aspect of the OS.

And other than the Perl support issue, I really don't care about the OS, as long as it does what I need and is painless to acquire and support. I can walk into my local Verizon store, hand my CC, and walk out w/ an activated VX6700 running WinMobile5 using my current phone number. And if things break, I can call VZ and bitch until they fix or replace it.
