due to architecture mismatch

 When building with +universal, fails to "configure", with error in
 main.log showing:


 {{{

 }}}

 If run with '''-universal''', it builds ok.

 The file '''VerifyFortran.f.o''' is x86_64 only - should it be i386 &
 x86_64 for a universal build? Maybe doesn't explain the above error.
 No idea how to fix or debug.
