I don't think so, no. The only way to actually use libqtm-11 or libqtm-12 seems to be to either set a run-time library path in the application, or to override the LD_LIBRARY_PATH in a startup script. Neither install anywhere in the default link path, so will never be used otherwise.

I'm not sure why it's working for some people though - either the CSSU version of the libqtm-location package is faulty, or they're somehow linking to the libqtm-11-location version instead. Rolling back to the old libqtm-location package didn't help though, so it doesn't appear to be (just) that.
