I am trying to rebuild a number of packages after an update and seem to be stuck with blockers on LAPACK and BLAS. I have read some other messages on this topic and they have not worked for me. So, i have cleaned out (emerge -C) everything with BLAS or LAPACK in it's name. I am now attempting to rebuild some things in this case numpy and still getting blockers. Here is what I get, is there a proper way to resolve this.

Code:

AsusTux ~ # emerge -pv numpy

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