I unmerged eselect-cblas and eselect-blas when I had similar problems, and I
think also {blas,cblas}-reference. The eselect packages got remerged
automatically, and some block I do not remember remained, but after some
days, a deep world update finally was working again.

This looks strange. A target in the root file system? Here the log continues
like this:
[100%] Building CXX object

[100%] Building CXX object

No. All I can say is that I just emerged gmsh without problems on ~amd64,
both with and without the blas USE flag. The other USE flags are those:
Installed versions: 2.5.0{tbz2}(23:10:59 26.08.2011)(X blas jpeg png
zlib -cgns -chaco -doc -examples -lua -med -metis -mpi -netgen -opencascade
