Maybe.  math/lapack is built with gfortran, which is from
lang/gcc47 on my system.  lang/gcc47 is probably picking 
up the installed devel/binutils.  This would explain the
/usr/local/bin/ld instead of our /usr/bin/ld.   libc_p.a is
built with clang, so I'm probably running into yet-another
clang vs gcc problem.
