 This patch is a fix for Ubuntu 11.04. Ubuntu already patch their python
 like this.  It is not a python bug. It is the Ubuntu+python combination,
 see the above thread for an answer I got from bugs.python.org.

 If this harms building on other systems, I can make it specific to
 checking the Ubuntu version and only then applying the patch (using
 lsb_release -d).

 == Note for the release manager ==

 Not ready for merging

Comment:

 The sage subshell does not find lsb_release.
