Comment(by vince@…):

 Ok, I know this. What reports otool -L ${prefix}/lib/libptf77blas in your
 case? Here is mine:

 {{{

 otool -arch i386 -L libptf77blas.dylib
 libptf77blas.dylib:
         /usr/pkg/lib/libptf77blas.dylib (compatibility version 0.0.0,
 current version 0.0.0)
         /usr/pkg/lib/gcc45/i386/libgfortran.3.dylib (compatibility version
 4.0.0, current version 4.0.0)
         /usr/pkg/lib/libatlas.dylib (compatibility version 0.0.0, current
 version 0.0.0)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 125.2.0)

 otool -arch x86_64 -L libptf77blas.dylib
 libptf77blas.dylib:
         /usr/pkg/lib/libptf77blas.dylib (compatibility version 0.0.0,
 current version 0.0.0)
         /usr/pkg/lib/gcc45/libgfortran.3.dylib (compatibility version
 4.0.0, current version 4.0.0)
         /usr/pkg/lib/libatlas.dylib (compatibility version 0.0.0, current
 version 0.0.0)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 125.2.0)

 }}}

 You see that the two versions (one for i386 and one for x86_64) link to
 the appropriate version of libgfortran.dylib. But, AFAIK, these two
 libgfortran libs are not generated unless you specify --enable-multilib
 when compiling gcc (without --enable-multilib, you get the one your
 default arch requires). Is your gcc44 built universal?
