Found another Win32 problem in MakeMaker. ExtUtils::Install is using the Unix path seperator on Win32. Patch as follows --- ExtUtils-MakeMaker-6.16/lib/ExtUtils/Install.pm 2003-06-05 10:04:31.000000000 +0200 +++ ExtUtils-MakeMaker-6.16-pathced/lib/ExtUtils/Install.pm 2003-09-08 11:58:26.000000000 +0200 @@ -15 +15 @@ -my $splitchar = $^O eq 'VMS' ?

E:\.cpan\build>perl -MConfig -e"print $Config{path_sep}" ; Is there some reason that value can't be trusted? Also I kinda think that File::Spec should have a path seperator method that does the right thing per OS. It seems to me that it is reasonable to have this piece of information encoded into File::Spec, or even better a method for splitting things like $ENV{PATH} and $ENV{PERL5LIB} that would Do The Right Thing in a portable way. I know that ive seen this particular piece of logic in a lot of code, and IMO it makes sense to factor it out. Cheers, YvesThread Next
