Yes, it is in fact part of the gsl package. It's just that somehow it is not correctly linked.

nicolas at linux-cwbq:~> rpm -ql gsl
/usr/bin/gsl-histogram
/usr/bin/gsl-randist
/usr/lib/libgsl.so.0
/usr/lib/libgsl.so.0.15.0
/usr/lib/libgslcblas.so.0
/usr/lib/libgslcblas.so.0.0.0

Is it difficult to try the above mentioned switch? I guess changing the gsl flags when gsl is found should do the trick...
