Hardy is old indeed and it is likely a missing package pb.

If you can stick to a recent Ubuntu release it will help a lot I believe,
since there may be some roadblocks to build this package for Hardy ( the
actual issue with rql is that it tries to use gecode ( a c++ constraint
solver ) and the gecode that ships on Hardy is old. The logilab.constraint
package can be used alternatively when using a source based environment).

Hence, if you insist on working on hardy, one possible working path is to
use the sources.

You may want to clone cubicweb and use the cw/bin/clone_deps.py script to
fetch all public cubes, and then manually install rql.

(but not sure if it is worth the pain wrt switching to something more

We will help of course. Just ask questions as they come.
