Comment:

 Ok, but we still have a problem for ports that specify a compiler that
 won't work.

 For example, [ticket:62480 py-numpy specifies clang37] which won't work on
 arm64. Fine. The port can't be installed and should emit an error ''when
 the user attempts to install it''. But it is ''not'' fine that the port
 fails to work at all, even to the point that port info doesn't work:

 {{{
 % port info py39-numpy
 Warning: Compiler gcc44 not available for Darwin20 arm
 Warning: Compiler gcc45 not available for Darwin20 arm
 Warning: Compiler gcc46 not available for Darwin20 arm
 Warning: Compiler gcc47 not available for Darwin20 arm
 Warning: Compiler gcc48 not available for Darwin20 arm
 Error: Unable to open port: Compiler clang37 not available for Darwin20
 arm
 }}}

 It's not fine that if I schedule a batch of port builds and one of them
 depends on py-numpy the entire batch fails to be scheduled:
