Although this symptom does look suspiciously like the problem David is
referring to, I don't think it is your problem because you are using IDL
6.0.

I would guess that your C program is running in an environment that does
not have the IDL_DIR environment variable set. The IDL routines you are
calling cannot find the fonts because this environment variable is not set
and they have no idea where to look. Try setting IDL_DIR to the IDL
installation directory.
