I just now attempted to emerge mod_perl, and had it fail early. Apparently it's touchy about a perl module Errno.pm It makes reference to a kernel version I no longer even have installed, in the file /usr/lib/perl5/site_perl/5.8.8/Errno.pm.
So I tried to get to CPAN to see if there was something I could download. It has the same problem. Now here's an odd thing. The version of Errno that's failing is timestamped August 14th. A version with the current architecture, timestamped today, exists at /usr/lib/perl5/5.8.8/i686-linux-thread-multi/Errno.pm I don't see immediately how to get my system sane again. I could just copy the Errno.pm, but I'm not sure that's wise. Anyway, the emerge failed like this: >>> Compiling source in /var/tmp/portage/www-apache/mod_perl-2.0.3-r1 /work/mod_perl-2.0.3 ...
