Found it! In alternatives.bash.in we have:
ALTERNATIVESDIR_ROOTLESS="@sysconfdir@/env.d/alternatives"
ALTERNATIVESDIR="${EROOT}${ALTERNATIVESDIR_ROOTLESS}"

EROOT is basically the prefix path, so the idea is you add
the prefix in the second line. Except that @sysconfigdir@
already include the prefix....
So instead of looking for alternatives in:
/Users/frb15/Desktop/Gentoo/etc/env.d/alternatives
it looked for them in:
/Users/frb15/Desktop/Gentoo/Users/frb15/Desktop/Gentoo/etc/env.d/alternatives

getting rid of one level of prefix in alternatives.bash got
me some working eselect for blas (reference), cblas (gsl) and lapack
(reference).

I'll leave bicatali to make the fix he deems appropriate.
