run script

Am running a fedora-based appliance in a VM (using VMware Player). When trying
to compile C programs, I receive the following error message:

I've attempted this with the simplest program I can think of, using no flags,
in the hope that this makes tracking the bug easier(?).  HAve also attached the
run script (can't attached preprocessed source as only allowed one attachment
at a time...?)
