In the future, please use WikiFormatting, fill in the Port field with the port that failed and Cc the port maintainers (port info --maintainers llvm-3.1).

llvm-3.1 is not supported per the error:

Error: llvm-3.1 is not supported on Mavericks or later.

You do not need it however. The ports that require it, ld64 and cctools, use llvm-3.3 by default now and so should you.
