When emerging cabal-3.0.1.0 with ghc-8.10.4, cabal complains: Warning: Unknown/unsupported 'ghc' version detected (Cabal 3.0.1.0 supports 'ghc' version < 8.10): /usr/bin/ghc is version 8.10.4 Later, portage stops with an error: setup: Encountered missing or private dependencies: base >=4.3 && <4.14 I can't test right now whether the error disappears when downgrading ghc, but I thought that it might be useful to add <dev-lang/ghc-8.10 as a dependency to cabal-3.0.1.0.ebuild.
Thank you for the report. We need to have all information at hand before ticket assignment. That is why I ask you to * attach the logs and * paste the emerge info as described on https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket Please reopen this ticket (Status:UNCONFIRMED) afterwards.
