I would like to replicate all this on a new PC that is running Windows XP-64Easiest way to do that is to run, on your Win XP-64 box, a perl that was "built for MSWin32-x86-multi-thread". That doesn't give you an x64 build of perl, but it does work fine on your Win XP-64 box, and it does allow you to easily achieve the replication you seek.
I saw a post from Jan Dubois recently, indicating that the PPM repository will soon be expanded - but, as
BrowserUk pointed out, that repository is currently very limited.
If you have ActiveState's x64 build of Perl, you could install the Platform SDK for Windows Server 2003 R2 compiler and try building Tk form source. Out of curiosity, I'm building Tk-804.027_500 with that 64-bit compiler for x64 ActivePerl right now. The build process ran for a while, but has just terminated with
c:\_32\comp\Tk-804.027_500\PNG\zlib\zconf.h(289) : fatal error C1083: Cannot open include file: 'unistd.h': No such file or directory. I have to head off to work - I don't have time to even think about that error at the moment.
Cheers,
Rob
