[phenixbb] GUI problems

Hi I've just installed the Linux 64-bit version 1.4-105 on a CentOS5 machine, and I get a lot of errors in starting up the GUI. What am I missing? Also is it possible to install both the 32-bit & 64-bit versions together: I know it works for the executables in build/intel- linux-2.6 build/intel-linux-2.6-x86_64, but does that mess up the gui? It's OK on the command line Phil
