1.0.35-r3 was working fine. when i merged 1.0.39, things stopped working, because it could no longer find the modules for RRDTool. with 1.0.39, RRDp.pm and RRDs.pm install in /usr/lib/perl. perl -V: @INC: /usr/lib/perl5/5.6.1/i686-linux /usr/lib/perl5/5.6.1 /usr/lib/perl5/site_perl/5.6.1/i686-linux /usr/lib/perl5/site_perl/5.6.1 /usr/lib/perl5/site_perl consequently, apps dependent on those libs fail. unsure what the fix is... but for now, i manually built symlinks out of /usr/lib/perl5/site_perl to the modules, and things work fine with that.
Dylan and I worked this out on irc - re-installed makemaker and all is well for him again. Updates are being re-added to the perl-modules eclass to try and encourage portage to correct this again.
