picpython missing

Hi, I attempted to use the latest passoft and pql linux rpms on a Centos 5.5 machine. pql and several of the other binaries give me an error message: pql: error while loading shared libraries: /opt/passcal/other/lib/libgtk-x11-2.0.so.0: ELF file OS ABI invalid I assume this means that the fedora 10 version is not going to work on a Centos machine and that I must install from source. I am attempting this now. My problem is that during compilation of passoft I get the following error message: /usr/bin/env: picpython: No such file or directory I've installed all the prerequisites listed. Is the picpython binary suppose to produced by one of the prerequisites? If so could you tell me which one? cheers, Ed Boring University of California, Santa Cruz
