>> one of the developers on their mailing list was kind enough to let me know that it doesn't yet compile under Perl 5.8.0.
I first read about Prima here about 15 minutes ago. Intrigued, I downloaded Prima-1.10-MSWin32-580.zip , unzipped it, ran the script ms_install.pl, changed directory to C:\Perl\site\lib\examples and tried several examples ... all in less time than it took me to write this up.
I have perl, v5.8.0 Binary build 806 on my machine.
True, I did not try to get the sources and compile Prima, so I cannont vouch for that :-).
