My first step to solve problems is to mask
app-admin/eselect::gentoo
Second we should maintain and distribute a package.keywords list
for the blas/lapack stack, we could alternative distribute a 
package.mask
for the main tree blas/lapack stack.
Bear in mind that we cannot mask the main tree blas/lapack stack from
the overlay's profile. Such a package.mask only affects the overlay.
So in any case you will need to explicitly copy or link to a provided
file (whether it is a mask or a keyword file).
