Hm. The MD5 module doc says it is deprecated and now just a wrapper around Digest::MD5, which is properly listed as a prerequisite. Did CPAN offer to install Digest::MD5? Did *that* install fail because of your INC problem? From the above, it looks as if Digest::MD5 should have been found if it installed under either /usr/local/bin/lib or /usr/local/lib. ??
