I'll bet I can guess, the relevant parts at least. He's using Ice
3.4.2 and GCC >= 4.7. This is a nasty issue because of the default
versions of many deb packages that don't actually work together.
Either updating to Ice 3.5 or downgrading GCC to 4.6 will solve this
issue. We were hoping for a patch against Ice 3.4.2, but I don't think
that's going to happen.

Now, PyBOMBS is set to look for Ice >= 3.5, though, so we still need
more information. My guess is that you have Ice 3.4.2 installed on the
system already and for some reason, GNU Radio is finding that and not
3.5, even though the script is supposed to look for 3.5 before
anything else.

In a slight look inside the process, I think it's time I do a blunt
check for the GCC version if Ice 3.4 is found. I was holding off on
this in hopes that a) it would be fixed in Ice and b) getting the
compiler version isn't exactly simple. (Cmake does have a variable
that holds the value of the compiler version, but it's only made
available in newer versions of cmake, which we are not requiring yet,
so we can't use it). But since it's only a problem if GCC is used, I
can parse the version string from it and get the info I need. Much
better to disable ControlPort in this case than to fail during
compilation.
