llvm versions on 10.5 3.9->8.0

[Riccardo Mottola via macports-users]

Hi,

when running upgrade of llvm 3.9, I get this message:
$ sudo port -v upgrade llvm-3.9
--->  llvm-3.9 is replaced by llvm-8.0

is this correct? I think that for now the different clang versions 
would "stay" and so corresponging also llvm.

I have clang and llvm 5.0 on 10.5 on Leopard which is I think the 
latest I can get.


another port (cfitsio) pulls in llvm 9.0 and I tried to compile that 
and it fails. I did not try 8.0 to be honest.
