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

 Here is the result:

 During the call to ld, I included -L${prefix}/lib/gcc${gccnumber}/${arch}
 before[[BR]]
 -L${prefix}/lib/gcc${gccnumber} so that -lgfortran would find the correct
 architecture library.

 I must admit that I do not know much about --enable-multilib, but I have
 not changed the gcc44 port,[[BR]]
 and I seem to have both libraries.
