From the thread at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=456898 I see that this problem is known and fairly specific to gsl, which provides a rather non-standard way of exchanging implementations of the cblas lib post-compilation.

> Peter, could you try to add that to cmake so that I can check whether it works? Having all fit plugins crash is really bad. We should try to fix it, especially if there is a known solution. I'm actually surprised that it does not crash on other Linux systems as this way of linking seems to be the default for gsl.

As I understand it, gsl loads a blas lib at runtime. Have you installed one of them on your sytem?
