How could that have happened? Note, this is not the intel compiler,
so flags like "-cxxlib-gcc" shouldn't be a problem here. Could the
build system use so different flags that the resulting libraries
wouldn't be interoperable? (I know this can happen rather easily
on other systems. However, I haven't seen that with gcc on Linux
as long as you stick to the same compiler version).

Python was compiled using gcc 3.3.4. Could this cause the problem?
(I don't think so.)
