As for the OP's problem, almost certainly a library dependency issue (use LD_DEBUG=all to get more information, or just use the calibre binary packages and save yourself lots of headaches).

Qt workarounds are in the calibre source code itself.
Install-from-source is officially sanctioned and is supposed to get you the same results as the binary packages -- absent downstream bugs introduced by packagers.
