Re: [gentoo-user] Problem with cblas libraries

[denis cohen <denis.cohen@gmail.com>]

Thanks to all that responded. I've tried

revdep-rebuild
emerge --depclean
revdep-rebuild

with no progress on the errors I have.
I've unmerged cblas* blas* gsl, synced, and "emerge -uDN world "also
without success (also tried cblas-external USE flag but could not see
it with eix).
eselect cblas also gave no results.

One problem I may have is with eselect. eselect-cblas has been
unmerged but trying to re-emerge it gives this block.


emerge -vp eselect-cblas

These are the packages that would be merged, in order:

Similar problem with eselect-blas and eselect-lapack. Any ideas before
I try some more unmerging?

Thanks
