cvxopt fails its self-tests only on OS X 10.7?
{{{-lblas}}} links against Apple's "classical" BLAS (which you call with
Fortran conventions), and use names ending with '_'. And
that's how CVXOPT makes these fateful calls to daxpy().
Actually, it occurs to me now that it's GSL extension of CVXOPT that needs
its GSLCBLAS, nothing else.
Sorry for noise. Please disregard my request on this.

> Anyway: let me also clarify that I'm simply restoring the old behaviour,
such that `cvxopt` builds with GCC 4.6.2. So if there really is something
to be done, I prefer to get this ticket reviewed as-is and continue on a
different ticket.
OK, I'll look into it ASAP.
