Thanks for the pointer. Right now that particular ebuild won't even install
because it assumes .so and linux.

First I want to solve the problem of eselect not listing stuff that is 
properly
installed. In particular gsl and blas-reference are installed properly, so are
their particular alternatives. Yet "eselect cblas list" and "eselect 
blas list"
return nothing. I think I have an idea of where the problem is. I just need a
bit of time to investigate.
