I'm unable to reproduce the problem. Please make sure the new ust was
completely installed with "make install" (older versions of the libs
lying around could cause this). Also, try to run ustctl with strace.
This will tell what socket file it's trying to open. You can then go
check if the socket file is actually where it's looking for it.

Thanks!
