All the stuff is here: https://github.com/Heather/gentoo-perl6
May be moved to overlay: https://bugs.gentoo.org/show_bug.cgi?id=463320
Some perl6 install utils must be patched upstream, for example ufo must install bins to /usr/bin -- work in progress
Tool to port stuff from ecosystem to ebuilds: https://github.com/Heather/CrystalMaiden -- work in progress
There are no much stuff yet but I suggest to Package (make non-9999) panda, ufo, and maybe some more modules.
9999 nqp and rakudo are also there.
Will keep it in my mind then, AFAIR, overlay already available through layman. I think no make sense for this bug.
yes, and it's pretty outdated and inactive now.
