Ok, now CMake builds volk without orc support and it seems to work.
Given that there isn't an updated orc package for Ubuntu 10.10, what's
the recommended course of action?

a) Live without orc support. Does it make much of a difference on x86?
The build-gnuradio script does not install or check for liborc.

b) Install orc from source. Messy, and causes problems if you later
install a package with a dependency on liborc.

c) Install a newer liborc package from a PPA. A quick search of
Launchpad didn't find any.

d) Get a newer distro. Personally I'm not ready to deal with this yet,
and I suspect many users feel the same way because Ubuntu 10.10 is the
last pre-Unity version.

Thanks,

Ian
