(taking to virt-tools-list, this isn't relevant to libvirt)

There must be an install issue, you shouldn't have this issue. My guess is
/usr/local/bin/virt-install isn't looking at the newly installed virtinst libs.

What command did you use to install? What distro are you on? What does:

python -c 'import virtinst; print virtinst'

show? It should list the path to the newly installed virtinst, the one via
your distro.
