Comment(by mcalhoun@…):

 Replying to [comment:7 vince@…]:
 > Ok, I am still puzzled that you can compile i386/x86_64 code without
 having the proper libs. For example, libptf77blas has a dependency to
 libgfortran, which is not universal unless you build it with --enable-
 multilib. Yet, I might be wrong.
 The muniversal PortGroup basically performs the configure, build,
 destroot, and test phases twice.[[BR]]
 The first time, -m32 is passed to the fortran compiler to build i386 or
 ppc libraries.[[BR]]
 The second time, -m64 is passed to build x86_64 or ppc64 libraries.[[BR]]
 After the destroot phase, the muniversal PortGroup merges the two
 installations using, among other things, lipo to form a universal
 installation.
