[PyQt] Is the download of sip and pyqt4 the same for 2.7 and 3.2?

[Scott Kitterman]

I tried this out in an 11.04 chroot.  Things that get overwritten from the 
distributionPyQt package:

 /usr/share/sip/PyQt4/
 /usr/bin/pyuic4
/usr/bin/pylupdate4
/usr/bin/pyrcc4
/usr/lib/qt4/plugins/designer/libpythonplugin.so (designer plugin)

Except for the designer plugin, these are all shipped in separate packages 
called pyqt4-dev-tools and python-qt4-dev that are only used for development 
support.  On that basis, I think it's very unlikely that building the python3 
version from source would break your system, but keep in mind that this is 
unsupported (from my POV anyway) and if you do break it somehow, you get to 
keep both halves.
