I am not sure about this. I have managed to install quite a few modules from CPAN on Win98. I have only had one or two problems with CPAN modules.
However, that reference to miniperl is interesting - I remember something about miniperl in this month's
TPJ. I think that miniperl is something to do with building Perl, but I can't rememeber - the article was quite technical and I have never built Perl before!
