Great, I will do a basic test later, to see if the application starts. Just no 
ships here around, real reception trials have to wait :)

Just FYI, I've added the things I needed to add to get gr-ais working against 
mainline Gnuradio again. I've tested with USRP1 and N210 and it works OK here. 
More testing is of course welcome.

Yes, this is my fault. I've been catastrophically lazy about removing the 
commits to gr-ais's trunk in order to make it work with mainline GR, because 
I've been hoping things would have been integrated sooner. Tell you what, I'll 
create a branch of gr-ais which just includes the required blocks, in-tree, and 
push that to the trunk until we get all the GR work sorted out. It's going to 
take me some time though.

I hit this myself just recently.

Apparently, trunk gr-ais is “too new”: it requires a block 
gnuradio.digital.msk_correlate_cc, which was proposed but not yet merged:
https://github.com/gnuradio/gnuradio/pull/376

I, too, would like to use gr-ais and hope this problem gets resolved soon 
(either by gnuradio accepting the patch or gr-ais offering a “stable branch”).
