 Replying to [comment:6 kencu]:
 > without some further (serious) sorting out, you are stuck installing gcc
 and clang and llvm as universal, even though most of our gcc ports do not
 actually install themselves as universal in so doing ("Lies to MacPorts,
 as Ryan likes to say") and clang/llvm have no need to be built as multiple
 architectures, being native cross-compilers --- but these things would
 need to be better sorted out for this to actually work right.

 want to build anything universal with them.

 Thank you for detailed explanation.

 So since I do require gcc7 to build R, and you say gcc then has to be
 universal, I am running into the same problem with python27. I did add a
 line in a portfile, but when I invoke a call to upgrade gcc7 as universal,
 python27 starts downloading and fails to build.

 I used this command:

 sudo port -v upgrade --enforce-variants gcc7 +universal
