Actually, it seems that I only have version 1.46 libraries installed,
see the attached file.

This is really screwed up: I have libboost-dev installed, which
according to synaptic is at version 1.48.0.2. Looking in the package
info I see that it depends on libboost1.46-dev, which explain why all
my boost libs are version 1.46. The same applies to many other boost
packages, e.g. libboost-thread-dev.

Cmake didn't complain about bad boost version and I can see no version
info in CMakeCache.txt. Gnuradio compiles and install just fine. I can
rerun cmake and submit the cmake files on a system with boost 1.46 if
needed.

I have uninstalled the 1.46 libs manually (except those that are
required by some applications) and the installed libboost-xyz1.48-dev
libraries. recompiled uhd and gnuradio and it seems the run-time issue
I was having before (app freezes) is now gone.
