lovely error message from CPAN

Undefined subroutine &Compress::Zlib::gzopen called at /opt/local/lib/perl5/5.8.8/CPAN.pm line 5721

no solution, yet!

my best wild guess is that port/CPAN has broken the installation of CPAN/port.

Should I use cpan or port ?
May I use both ?
Since I'm not binded to any version in particular I could probably u

se both...
