GCC 4.0.1 does not support OpenMP. GCC 4.2.1 _does_ support OpenMP according to its man page:
-fopenmp Enable handling of OpenMP directives "#pragma omp" in C/C++ and "!$omp" in Fortran. When -fopenmp is specified, the compiler generates parallel code according to the OpenMP Application Program Interface v2.5 <http://www.openmp.org/>.<omp.h> does exist:

What do I miss here?
It might be a bug in the AX_OPENMP autoconf macro (in m4/ax_openmp.m4). The first thing that comes to mind is that it relies on $IFS being set to space. Do you modify $IFS anywhere in the OSX build script?
no modifications of $IFS I'm aware of:
suv$ echo $IFS | cat -e $ suv$ env | grep IFS suv$ suv$ set | grep IFS IFS=$' \t\n' suv$ grep IFS packaging/macosx/*.sh suv$
nothing special here AFAICT, using bash:
suv$ bash --version GNU bash, version 3.2.17(1)-release (i386-apple-darwin9.0)
