I thought Pavel was talking about 11 somehow...
I am sorry, It was not clear - I talked about master

That was intentional, even though it perhaps should be better documented. That allows a distro to build and distribute pg without llvm enabled, but then have the JIT package with all the dependencies separately. The pg yum packages do so.
I don't like this solution - it is safe on production - but it can breaks my development environment - or we need to change setup and make install will not be enough.
