rhpl-0.122.1-2 claims to depend on /usr/bin/python2.2, but it installs its python modules in /usr/lib/python2.3. I discovered this because redhat-config-printer is trying to use the iconv python module, which isn't available to it because I have python 2.2 installed and python 2.2 doesn't look in /usr/lib/python2.3.
This is fixed in 0.122.2
