Try clean build as Anton suggested, scons might miss changed dependency
or such. Otherwise, inspect full command-line of compiler (brief=0, you
know) and try running it by hand, if it works.

IIRC gomp is not linked to explicitly, but is added automatically by
specifying -fomp to the compiler (which is done if there is the openmp
feature automatically). Didn't you add -lgomp by hand somewhere?
