Deprecated module md5 with python 2.6

This is no longer throwing warnings on builds, but rather throwing errors and causing cascading build failures in jaunty-autotest:

   dh_pysupport -v
 pysupport-movemodules debian/libaa1-dev
/usr/bin/pysupport-movemodules:8: DeprecationWarning: the md5 module is deprecated; use hashlib instead
  import os,os.path,md5,re,sys
Traceback (most recent call last):
  File "/usr/bin/pysupport-movemodules", line 8, in <module>
    import os,os.path,md5,re,sys
  File "/usr/lib/python2.6/md5.py", line 10, in <module>
    from hashlib import md5
  File "/usr/lib/python2.6/hashlib.py", line 136, in <module>
    md5 = __get_builtin_constructor('md5')
  File "/usr/lib/python2.6/hashlib.py", line 63, in __get_builtin_constructor
    import _md5
ImportError: No module named _md5
dh_pysupport: command returned error code 256
make: *** [install] Error 1

This needs to be sorted out ASAP in either python-support or python2.6, I'd guess, if we want to be able to rebuild anything that build-depends on python-support after the release. :/

The traceback looks like python's trying to import some backward-compat code and failing miserably, so maybe the critically urgent fix belongs to python here, rather than python-support.

Nevermind the severity inflation. The build logs where I saw the error look to be a case of "the package was partially removed, and python2.6 was no longer installed, but a less-than-clever debian/rules file conditionally calls dh_pysupport if the binary exists", hence the spectacular explosion.

This bug was fixed in the package python-support - 0.8.7ubuntu3

---------------
python-support (0.8.7ubuntu3) jaunty; urgency=low

  * use hashlib instead of the md5 module (LP: #340757)
  * depend on python2.5 (because of hashlib)

I'm going to reopen this, since the fix in 0.8.7 is not correct. The attached one-liner patch will correct the problem.

This causes build failures for all packages using dh_pysupport, so raising to high.

I've uploaded the fix, waiting for another release team member to review.

This bug was fixed in the package python-support - 0.8.7ubuntu4

---------------
python-support (0.8.7ubuntu4) jaunty; urgency=low

  * Fix invocation of hashlib md5 in pysupport-movemodules; thanks to
    Kyle Ambroff <email address hidden> for the fix. LP: #340757.
