I seem to be o.k. now. I tried setup.py clean. That
> doesn't remove the build dir?
No, it only rebuilds what is needed, but if the recursive dependency
analysis is broken, you can get into an inconsistent state. This
happens most commonly when headers are modified, because this doesn't
trigger rebuilds of the *.cxx files that include them. In this case,
I rebuilt the swig runtime headers with a more recent version of SWIG
to help Charlie try and get python2.5 builds going.
Note to other svn users: flush your build subdir before trying to
rebuild after a recent svn update.
