I am now having some troubles initiating the most updated nightly built dev-2247. I have to use this version because it is supposed to have a bug fixed based on my bug report in November. My machine is running Debian 7 with kernel version 3.2.0-4-amd64. And the pheinx installation file I downloaded is the 64 bit linux version for CentOS 5. The symptom is that after I called phenix from a terminal window, there is an error message saying "local 'en_GB' cannot be set" (which is always the case and which does not seem to matter). After that, phenix GUI did not start at all, but ps command shows two python2.7 processes running. Running phenix from command line seems to work fine. Before switching to this version I was running the stable version 1.10.1-2155, and have no problem.
