How about the package 'gnuradio-companion' - the one just before gr-fec
- does it find gsl?

There should be a couple of lines at the end of 'gnuradio-companion':

 -- checking for module 'gsl >= 1.10'
 --   found gsl , version 1.16
 -- Found GSL: gsl;gslcblas;m

Is it possible you have libgsl (gsl) but not libgslcblas (gslcblas)?

Incidently, what version of gnuradio are you building?
