Yes, you have ppm3. That's the version not on CPAN. Anyone can get it from http://downloads.activestate.com/PPM/. IIRC, ActivePerl 5.6 originally came with ppm2 (still called it ppm), while ActivePerl 5.8 came with ppm3.
 
If, given your detective work above, B::Generate builds elsewhere but not on Win32, then the problem lies not in the module, but in the Module::Build mechanism for Win32?
No, Module::Build is not the problem, and neither is win32. It shouldn't build on any platform ( 'fold_constants' isn't exported anywhere). From what I can tell you'd have to build from the perl (5.8+) source tree (PERL_CORE), and you'd have to link in op.obj, but there is no mention of this anywhere.

Or, you have to build a perl which exports fold_constants (or Perl_fold_constants).

Maybe you need to build a new perl? Hmm, yeah, maybe you need to make perl. I can't tell, nor can I test (that part is horribly broken on win32, use of cat everywhere, excedes commandline (i got tons of extensions installed) ... horrible).

MJD says "you can't just make shit up and expect the computer to know what you mean, retardo!"
I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).
