My guess is that ActiveState built your Perl with MSVC6 and the free MSVC tools are MSVC7. The two are not binary compatible. I recommend using the same C compiler for building Perl and all Perl extensions.

If you want to compile your own extensions you will thus have to compile your own Perl as well, which also means that you can't use any premade PPMs anymore.
