 I should add, unless the module in question exists elsewhere because it
 was built previously.  The module isn't built in the python26 package,
 so it shouldn't be tested, true, but the test was finding the pre-
 existing pyexpat package in my environment and making use of it.  (So
 the path to search for modules needs to be sanitized too, for testing.)
 
 I tested before and after situations with a VM image of 5.99.27/amd64.
 If I test with 2.6.4 and py26-expat from a vintage of several months
 ago, test_pyexpat.py works as expected.

 If I test with 2.6.5 and py26-expat from today's pkgsrc, I end up with
 a crash.

 Steps to reproduce:
 
 -Build lang/python26.
 -Build textproc/py-expat.
 -Run the test_pyexpat.py test.  (It's installed in =
 pkg/lib/python2.6/test/.)
 
 I'm seeing this with both 5.1_RC1/i386 and 5.99.27/amd64.
