I can not install reference implementations of lapack / blas anymore, further gsl does not provide a cblas for eselect-ldso anymore. This makes it virtually impossible to install any other version of lapack then sci-libs/lapack-3.8 on the system, especially if you want to emerge sci-libs/scikits_learn. 1 ) if lapack-3.8 is the reference implementation then it should be renamed to lapack-reference 2 ) you should be allowed to still install fortran reference versions and permit gsl to provide cblas Reproducible: Always Steps to Reproduce: The following happens trying to emerge lapack-reference emerge -pv lapack-reference These are the packages that would be merged, in order: Calculating dependencies... done!

Hi Thomas, (In reply to Thomas Haschka from comment #0) > I can not install reference implementations of lapack / blas anymore, > further gsl does not provide a cblas for eselect-ldso anymore. > > This makes it virtually impossible to install any other version of lapack > then > sci-libs/lapack-3.8 on the system, > especially if you want to emerge sci-libs/scikits_learn. > > 1 ) if lapack-3.8 is the reference implementation then it should be renamed > to lapack-reference Lapack-3.8 is the reference implementation. The upstream is named lapack. The tarball also includes BLAS. Therefore we decide to merge cblas-reference, blas-reference and lapack-reference and rename it back to sci-libs/lapack. > 2 ) you should be allowed to still install fortran reference versions lapack-3.8 has both the fortran and c reference versions. > and permit gsl to provide cblas Sorry we decided not to do so. See bug 688742 for details. Benda
Marking as resolved-fixed as the comments by the gentoo developer were informative on how gentoo handles blas/lapack right now.
Thanks Thomas!
