On Linux Itanium (ia64) systems, sympow builds with gcc 4.6.0 but fails doctests. Example from cleo (RHEL 5.3 ia64 Itanium 2):

sage -t -long  -force_lib devel/sage/sage/lfunctions/
File "/home/buildbot/build/sage/cleo-1/cleo_full/build/sage-4.7.alpha5/devel/sage-main/sage/lfunctions/", line 213:
    sage: sympow.modular_degree(EllipticCurve('11a'))
Exception raised:
    Traceback (most recent call last):
