Here's the errors I get-

clang: error: linker command failed with exit code 1 (use -v to see 
invocation)

Not sure what to make of that- thoughts?

Also, this is probably a stupid question to be asking now, but is
there a more supported version than tip-of-tree? I tried the 2.7
tarball and wound up with a different set of errors.
