ByteLoader, as you know, is now part of B::C. Unfortunately, there doesn't seem to be a ppm for B::C at the ActiveState repo, or at any of the other repos, for that matter.

It's being a bit troublesome for me to build on ActivePerl, with many of the tests segfaulting, but it builds fine (though somewhat noisily, and the tests take a long time to run) on Strawberry Perl if you're interested in going down that path.
At least, the tests terminate with the claim that they all passed, though this looks a bit suss to me:

t/bytecode.t ...... 32/39 Can't locate qr_loaded_module.pm in @INC (@I

t/bytecode.t ...... ok

But, for the moment at least, it seems your best milage wrt ByteLoader will be with Strawberry Perl.

Not sure why ActivePerl is being unco-operative .... interesting ... and probably worth a further look when I get a chance.
