Can you let me know if Ice 3.4.2 is also installed on your system?
Most likely it would have been through apt-get, so just see what
'aptitude search zeroc' comes back with; hopefully it says that
zeroc-ice34 is installed. If that's the case, then cmake is likely
finding that version of Ice and not 3.5.1.

You can also check to see what cmake found in CMakeCache.txt in the
build directory and looking for ICE. Or look at the output of cmake
when configuring GNU Radio and you'll see "Ice-3.4 found" or "Ice-3.5
found".

If it's actually trying to build off Ice 3.5.1, then we have a new
problem. Otherwise, it's a matter of getting cmake to find the correct
version of Ice, which might mean updating the recipe to explicitly set
the version info.
