I'm guessing that the GNU Radio files are in /usr/ and the OsmoSDR files
are in /usr/local. In that case, GRC doesn't look for the blocks in
/usr/local.

To see if this is the problem, set the environment variable
GRC_BLOCKS_PATH to /usr/local/share/gnuradio/grc/blocks/ (or wherever
your blocks are) and start gnuradio-companion. If this works, then you
can statically set this path in ~/.gnuradio/config.conf (see
http://gnuradio.org/redmine/projects/gnuradio/wiki/GNURadioCompanion).

This behaviour is already documented (Issue #606), but we get very few
people who mix the source and binary builds.

Well, if GNU Radio doesn't work you won't be able to use gr-osmosdr
either. I can't think of a solution off the top of my head, though.

Perhaps this is a case where pybombs might be able to help you.
If you want to try this, do the following:
- Uninstall everything GNU Radio- and OsmoSDR-related
- Run
git clone git://github.com/pybombs/pybombs
cd pybombs
./pybombs install gnuradio

and then

./pybombs install gr-osmosdr

http://gnuradio.org/redmine/projects/pybombs/wiki/QuickStart will guide
you.
