It looks like ACX_BLAS finds the Fortran BLAS.  You'd need to check
for CBLAS libraries.

Possibly the gsl.m4 macro is more than most people need these days,
since it checks the version numbers.  This was more important in 0.x
when the API was changing.

Now it is probably sufficient to use the standard autoconf macros to
find GSL and a CBLAS library.
