I have now removed the threads USE flag from openmpi, but 'emerge
tachyon' still fails with the same error:
root@caiman:/root(26)# emerge -vuND sage
These are the packages that would be merged, in order:

Hi,
you have to find a combination of USE flags which work together. In
your case, I
suggest removing the mpi flag and keeping the opengl and threads flags. This
will enable accelerated rendering with OpenGL and threads - which will not
work with the Message Passing Interface (MPI).
When I wrote the tachyon ebuild it was not easily possible to define a valid
combination of USE-flags and I have to admit the current solution is not the
best. I think with EAPI=4 it should be possible to find a better approach.
Cheers,
Christopher
Hi Christopher,
I understand, that I should remove the mpi USE flag from tachyon. I did this.
Then I suppose that the global thread flag does not mean any problem,
So I deleted again the removal of the thread USE flag from openmpi.
With this settings I was able to emerge tachyon-0.98.9-r1.
