Comment (by michaelld@…):

 Default variants are +clang +lapack, not +gcc5 +lapack.

 Both the release and devel build for me either default variants, or with
 +gcc5 instead of +clang. The primary difference in that specific compile
 command in the log file between mine and yours is that mine has:
 {{{
 -L/opt/local/lib/gcc5/gcc/x86_64-apple-darwin15/5.3.0
 -L/opt/local/lib/gcc5/gcc
 }}}
 both before and after `-L/opt/local/lib`. Yours just has these after, not
 before. I've no idea how to correct this issue if it even is one -- which
 I'm guessing this isn't the actual issue. That said, I'm at a loss as to
 what might be the actual issue. OpenBLAS is a very complex project!
