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. > Not sure that was a good idea because now, even if I've reinstalled > these packages, > I am having several new problems: > > - compiling gcc with the gsl library spits out errors like: > g++ -L/usr/local/lib -lm -lgsl exact.o > /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/../../../../lib64/libgsl.so: > undefined reference to `cblas_ctrmv' [...] > and so on....... > > - still can't re-emerge packages like gsl and gmsh.

Stop. This looks strange. A target in the root file system?

No. All I can say is that I just emerged gmsh without problems on ~amd64, both with and without the blas USE flag.
