Comment (by vince@…):

 Ok. Great. I think there is a conflict between the options -DATL_AVX and
 -msse4.2.

 -DATL_AVX is probably automatically added by Atlas as it detects that AVX
 instructions are successfully compiled, whereas -msse4.2 is the standard
 way to disable to use of AVX instructions with gcc4.8 and is part of the
 Portfile standard behavior.

 Since your installation is non-standard, I'd prefer to keep the Portfile
 the way it is. Is there a reason why you don't use 'clang' and the 'perf'
 option, which handles AVX cleanly by using the dragonegg front-end?
