Greetings,

A cblas library is needed to link with the shared gsl library
even if no cblas function is used, or when LDFLAGS="-Wl,--as-needed"
is used to build gsl. 

One possibility is to link directly either from an external
external cblas library or from the builtin gslcblas at compile time
instead of the GSL_CBLAS_LIB as suggested in gsl-config.

This could be done as a cblas configure option as proposed in the
attached patch (also in the Gentoo public cvs repository).

I hope you will find this useful.

Regards,
