No it should just work from the directory like it always did. HOWEVER if you have old .cl files in /usr/bin it might be using those. If you do make install with the binary version it will end up in /usr/bin (that's why I included the entire build tree this time instead of a stripped down tarball).
OMG what a total fail! I just downloaded and unpacked, copied my configuration and started with the usual scripts... Tried fiddling with config, then your suggestions, didn't work. Unfortunately, I failed to notice that I had downloaded the *source* release, no wonder the new terminal stays blank...

Nice going phase

Thanks though! Works like a charm!
