Seconded, I ran into the same problem some months ago when the 2011 version 
came out.

LIBRARY_PATH is needed at linking time. LD_LIBRARY_PATH is needed to find 
shared libraries at execution time.

Finally, if your projects have C/C++ sources too, you'll likely need to fix 
your C_INCLUDE_PATH too, or basic C headers won't be found either.

>From my Ada env setup file:

--8<--
# Fix paths for multiarch, broken since 2011 version
export C_INCLUDE_PATH=$C_INCLUDE_PATH:/usr/include/i386-linux-gnu
export LIBRARY_PATH=$LIBRARY_PATH:/usr/lib/i386-linux-gnu
--8<--

(And I haven't had to fix LD_LIBRARY_PATH yet... ?)
