Ok, trying to install amavisd-new from Dag. Getting into a lot of problems, all of which seem to stem from Perl dependency issues. I have built several of the required modules by hand, but then got down to perl-MIME-tools. It builds FINE, but will not install. Why?
Turns out, the perl RPM 'provides' perl(MIME::QuotedPrint)=3.01 but the module itself is 3.03. Build a perl module against MIME::QuotedPrint and you get a Requires:perl(MIME::QuotedPrint)>=3.03, which fails on installation.
CentOS 4RC1, perl-5.8.5-12.1
