Comment(by jameskyle@…):

 The atlas lib build scripts don't built dylib's. This is a step that the
 user on osx must take themselves and do manually. There's an errata on the
 topic that was used in the Portfile. However, the errata did not set the
 -install_name for when creating the dylib's and so my portfile also
 neglected this step. Toby pointed this out to me and I'm currently testing
 the revised build:

 {{{
   set ld "ld -dynamic -arch i386 -dylib -single_module -dead_strip -x \
           -all_load -L. -L${prefix}/lib/gcc43 -ldylib1.o
 -dylib_install_name"

   system "cd ${workpath}/${name}-${version}/build/lib && \
           ${ld} libatlas.dylib libatlas.a -o libatlas.dylib -lSystem \
           -install_name ${prefix}/lib/libatlas.dylib"

   system "cd ${workpath}/${name}-${version}/build/lib && \
           ${ld} libptcblas.dylib libptcblas.a -o libptcblas.dylib -latlas
 \
            -lSystem -install_name ${prefix}/lib/libptcblas.dylib \
            -compatibility_version 1.0.0 -current_version 218.0.0"

   system "cd ${workpath}/${name}-${version}/build/lib && \
           ${ld} libptf77blas.dylib libptf77blas.a -o libptf77blas.dylib \
            -lgfortran -latlas -lSystem \
            -install_name ${prefix}/lib/libptf77blas.dylib \
            -compatibility_version 1.0.0 -current_version 218.0.0"

   system "cd ${workpath}/${name}-${version}/build/lib && \
           ${ld} liblapack.dylib liblapack.a -o liblapack.dylib -lptf77blas
 \
           -lgfortran -lptcblas -latlas -lgcc_s.1 -lSystem \
           -install_name ${prefix}/lib/liblapack.dylib \
           -compatibility_version 1.0.0 -current_version 218.0.0"
 }}}
