Hi Volker - If GNU Radio is already installed into the PREFIX provided to cmake 
during configuration, then during "make test" some of the already-installed 
libraries will be found and used instead of those just build.  This condition 
can lead to some interesting "make test" errors!

I can say with confidence that the -built- libraries are all OK (I've checked 
both the CMakeLists.txt files as well as used ldd or otool to see what linkage 
is actually there; it's all good), it's just those found for -testing- which 
can get mixed up.

This is a known problem for a while now (to me), and in my queue to work on 
sooner or later.  I believe that the issue is more extensive than just adding 
VOLK to the library dependency list for each component.  I encounter this in 
MacPorts because, generally, the GNU Radio port is already installed when an 
update comes along.  The nice part is that it's trivial to replicate in 
MacPorts, and thus easy to see what needs to be fixed; and, the "how" part 
isn't too difficult either, just takes perseverance and time.

Thanks for the information and patch! - MLD
