Oh my, this is a mess. Trying to keep amavisd-new up to date, using the fine RPMs provided by Dag Wieers. First, apt-get tells me that amavisd-new is being held back because perl-Time-HiRes is less than 1.55. RHEL4 has an updated RPM, so download the SRPM from RedHat Network and rpmbuild --rebuild it, all is better, right? Nope, amavisd-new still needs perl(Digest::MD5) > 2.22. No handy rpm from RHEL4, it’s part of the main perl package. So, maybe I can just update it with CPAN (perl -MCPAN -e shell). After configuring CPAN, and remembering the odd commands to try an install, I get this error when doing install Digest::MD5:
Makefile:84: *** missing separator. Stop
Luckily, google seems to have indexed some new mailing list pages since the last time I searched for this, and I found this mailing list post. So, drop out of CPAN, export LANG=en_US, climb back into CPAN and now the build works. Silly broken multilang support.

Yay, up to date on amavisd-new. Now to get the other packages up to date and update the primary mail host.
