Comment (by barracuda156):

 Replying to [comment:5 kencu]:

 Haha, I have it already on PPC (both 10A190 and Rosetta). Now I am
 building for Intel, in a hope to cross-build `ghc` (which has to be built
 for x86_64 first before any attempts to cross-build).

 The problem is that Macports extrapolates a ban of specific `gcc-4.*` to
 `gcc10-bootstrap`, which is likely just a bug. If not, then a ban should
 be made conditional in `gcc10` and `gcc11` portfile, excluding cases <
 10.7. This problem has no direct relation to PPC.
