Here are some ebuilds for some perl modules that work, fairly minor, but they work.
Created attachment 224723 [details] Date::Calc perl module
Created attachment 224725 [details] Sys::Load perl module
Created attachment 224727 [details] Crypt::OpenSSL::AES perl module
I added keywords to Date-Calc. Sys-Load and Crypt-OpenSSL-AES seem not to be in the gentoo tree. You should open a bug for their inclusion against the perl team first.
Closing the bug as we (Prefix) are not the right persons to add packages to the main tree. Please file a bug for them against the perl herd.
