PPM was written by Activestate for their distribution of Perl. Are you sure that there are no licensing restrictions concerning its redistribution with other (non-Activestate) distributions?

As for a Fortran compiler... I can't imagine more than a few percent of Win32 Perl users requiring one. So for a broad majority of users, that will be unnecessary bloat, in a package that is already quite large.

Adam has put a fair amount of work into the build chain for Strawberry Perl, which opens up the possibility for you to create and distribute a Perl-Fortran distribution. You could call it Punched Card Perl (the initials can be read on two levels :)
