 > There won’t be any g95 needed. The problem arose from Apple breaking the
 Xcode, which made it impossible to compile gcc13 and some Clangs, then
 MacPorts could do nothing else but blacklist those compilers for the
 affected Xcode. R port and R PG assume a matching Xcode version, so things
 broke down, when users began installing Xcode 16, which triggered
 different blacklists. I.e. in result R and R PG blacklist gcc14 and ask
 for gcc13, but MacPorts itself blacklists gcc13 and earlier. Since no one
 remembered to blacklist g95, that gets picked simply because no other
 option was left.

 dependencies.

 Thanks for that - worked a treat. port wanted clang/llvm-17, and once that
 was done the R packjage with gcc14 support and NO g95 downloaded, and the
 build went without a hitch. And I've learnt a bit more about how ports
 work - bargain!b This was on macOS 14.7.1 and CLTs 16.1.

 Cheers,
 Alex.
