I've finally uploaded koji 1.15 to PyPi , so give it a shot!
For whom it is good:
Everybody using virtualenv's installations and koji xmlrpc client in
For whom it is not good:
Anyone who wants to install koji servers (hub, web, builders, ...) -
these are not included and we're not planning to release them this way.
Note, that official release channel is still pagure's releases page 
and rpms which can be created from these tarballs by running 'make rpm'.
Rpm installation is preferred one.
