А подскажите, что ему не так?
calculate abc123 # sudo emerge -av =net-im/skypeforlinux-1.5.0.3_alpha
These are the packages that would be merged, in order:
Calculating dependencies \
Invalid ebuild name: /var/calculate/my_overlay/net-im/skypeforlinux/skype-1.5.0.3_alpha.ebuild
... done!
emerge: there are no ebuilds to satisfy "=net-im/skypeforlinux-1.5.0.3_alpha"
