LLVM 3.3 failed

[Robert Broome]

I am trying to update ports after upgrading to 10.10 and XCODE 6.1.
LLVM 3.3 is failing.
According to the log:
import sys; print sys.version.split
has invalid syntax at sys.

configure: error: found python (opt/loca/bin/python); required >= 2.5

Does anyone have any ideas?

thanks
