After installing perl 5.10.1, all perl module ebuilds install to the root directory: $ ls / Test YAML.pm boot etc lib media opt root sys usr your YAML bin dev home lost+found mnt proc sbin tmp var Besides making a mess of root, perl cannot find the installed modules, because they're not in @INC. Reinstalling a 5.8-series perl did not fix it. Reproducible: Always Steps to Reproduce: 1. emerge yaml 2.
