Dear List This is killing me. I've been trying my best to install Authen::Radius manually from CPAN but I keep getting errors. Specifically, it can't seem to find MD5.pm. Output of ./perl Makefile.PL Checking if your kit is complete... Warning: prerequisite MD5 failed to load: Can't locate MD5.pm in @INC (@INC contains: /usr/lib/perl5 /5.6.1/i586-linux /usr/lib/perl5/5.6.1 /usr/lib/perl5/site_perl/5.6.1/i586-linux /usr/lib/perl5/site _perl/5.6.1 /usr/lib/perl5/site_perl .) at (eval 5) line 3.
