This is a continuing nightmare! Damn, I thought it was in a functional
state now.

The --with-gsl=DIR flag will try to find gsl-config in $DIR/bin:$PATH
... I guess that's not working? Possibly we should remove the appended
$PATH when searching, if --with-gsl was specified... can you try doing
that in m4/gsl.m4 for your NAF build and see if that works? You will
have to run autoreconf again. If that solves the problem, send me a
patch and I'll merge it into the M4 macro collection.
