Bug confirmed.

I'm having this problem with Blender as well, and I already have openmp compiled into gcc. Other programs with the openmp flag have not had this problem.

I was having the same problem. The simple fix was making sure the right gcc was selected with gcc-config. Be sure you're using >gcc-4.2.

I can confirm blender compiled fine using gcc 4.3.2 and failed with gcc 4.1.2. Please add a gcc check to the ebuild!
(In reply to comment #6) > I can confirm blender compiled fine using gcc 4.3.2 and failed with gcc 4.1.2. > Please add a gcc check to the ebuild! for @lu_zero (Luca Barbato): the OpenMP Standard v2.5 has been introduced into gcc from the version 4.2.0, so attached there is an ebuild patch for the blender ebuild that adds the gcc check. hope to be useful.

Is it possible to add another check, so the emerge prompts to use gcc-config to set the current gcc? If the user updated the gcc but didn't select the new version, the emerge just fails, even though gcc 4.3.x is installed (that error led me here :) ).
I have update gcc to 4.3.2, even tried to re-emerge it with openmp, but still receive that error. However, if I run scons inside the unpacked source, it compiles just fine. Seems like scons keeps on using the old gcc, or some other misconfiguration happens, but only when running from emerge.
This should be fixed with 2.63a and pkg_pretend checks.
