Okay, so in order to play with some new blocks I found, [gr-rds] (https://github.com/argilo/gr-rds) in particular. It appears I needed a newer version of gnuradio than I had previously built from git to get the Control Port functions these blocks require.
So, off I go and
git pull cd build rm -rf * cmake ../ make

Apparently, the debian build of ZeroC’s Ice lib is bad, simple enough to fix, if you don’t mind stuff accumulating in /usr/local! Go to ZeroC’s source download site and grab the latest tarball, unpack it.
I edited the cpp/conf/Make.rules to install to /usr/local/, change as you see fit, or leave it at the default.
Then gnuradio builds fine again!
