I don't know why PyInstaller is, but from the web site it sounds like it is a program that tries to get a program and all of its dependencies together. I bet that PyInstaller picked up an old version of libxcb and decided not to pick a suitable version of libX11. To confirm, I would suggest running 'find /home/vagrant/devel/RCM/ -name "libxcb*"' to see if it finds some other versions of libxcb.
