I first encountered the following when revising sage-core-4.3.5-r1 to allow backporting from sage-4.4.2 to sage-4.3.5 and it appears with sage-4.4.2. If I upgrade python to 2.6.5-r99 and rebuild sage-core, sage will not start. I get: ImportError Traceback (most recent call last) /usr/lib64/python2.6/site-packages/IPython/ipmaker.pyc in force_import(modname, force_reloa ---> 94 from qqbar import (AlgebraicRealField, is_AlgebraicRealField, AA, /usr/lib64/python2.6/site-packages/sage/rings/ring.so in sage.rings.ring.Ring.__getitem__ ( /usr/lib64/python2.6/site-packages/sage/rings/polynomial/polynomial_ring_constructor.py in PolynomialRing(base_ring, arg1, arg2, sparse, order, names, name, implementation) --> 355 R = _multi_variate(base_ring, names, n, sparse, order) /usr/lib64/python2.6/site-packages/sage/rings/polynomial/polynomial_ring_constructor.py in --> 453 from sage.rings.polynomial.multi_polynomial_libsingular import MPolynomialRing_ ImportError: /usr/lib64/python2.6/site-packages/sage/rings/polynomial/multi_polynomial_libs Setting permissions of DOT_SAGE directory so only you can read and write it.

I rebuilt cython with no effect. This is somewhat similar to a problem that was solved by appending "-fno-strict-aliasing" to the flags in sage-core; which is still there. None of this is present with python-2.6.4-r99.
