27 Thanks for the pointer. Right now that particular ebuild won't even install
28 because it assumes .so and linux.
30 First I want to solve the problem of eselect not listing stuff that is
31 properly
32 installed. In particular gsl and blas-reference are installed properly, so are
33 their particular alternatives. Yet "eselect cblas list" and "eselect
34 blas list"
35 return nothing. I think I have an idea of where the problem is. I just need a
36 bit of time to investigate.
