It depends on the compiler build. The version some (most?) people have of the gcc tools has a -lg2c that cannot be linked into a dylib. You seem to have one that does but no one else has reported success. Only a week ago someone reported being unable to build with the default configure settings on MacOS X for exactly this reason.

Correction: DSTEIN is part of LAPACK, not BLAS

In short, that is a MacOS error, for there is a reference implementation of LAPACK. It is compounded by an error in the error message. Have you reported it to `MacOS-bugs' yet? Please do so.

That's not what works for other people. Why is is necessary for you?
