[galaxy-dev] Fastx toolkit broken pipe

Hello, I've got a local install of galaxy with fastx tools installed. I'm getting a broken pipe error but I'm not sure why. I install fastx using the compiler outside galaxy and it was working fine inside galaxy previously. Fastx works fine via the command line. I've checked the xml files and I don't see how galaxy cannot find the commands. I am running this off and external volume, but I don't think that matters. Cheers Ian
