Date: Sat, 2 Oct 2010 12:51:03 +0200 Randomly the build failed for me with the following error message.
libpython2.6.so: undefined reference to `_PyParser_Grammar'
The applied patch in [5] tried to fix this problem, but it turns out that this
was due to a possible race and already known in OpenOffice too [3].
R. David Murray (dmalcolm) <[email protected]> fixed this in Fedora
[1] and I applied his patch.
I reported this issue upstream [4] and this will only be fixed in Python 2.7,
so we have to keep this patch for Python 2.6.
