pybuild installation directory

[Jeremy Sanders <jeremy@jeremysanders.net>]

I'm trying to update the veusz package to use python3 and pybuild. It 
seems be default that pybuild installs in 
usr/lib/python3.X/dist-packages/veusz.

As far as I can see, the package should be installed in in 
usr/lib/python3/dist-packages/veusz. There's both arch-specific and 
non-arch-specific code.

Is this correct? What's the proper way to fix this? I'm doing this

	dh $@ --with python3 --buildsystem=pybuild

Thanks!

Jeremy
