Geomview External Modules

[Y.Zheng at swansea.ac.uk (yao zheng)]

On 14 June, I reported a problem with external modules of 
Geomview.1.2.3. However, I have solved it now.

The problem I was facing is that geomview could not invoke 
external modules, and dumped cores from these modules.
-----------------------------
    Core from signal SIGSEGV: Segmentation violation
    emodule_run(em=0x6900d080) ["comm.c":345, 0x401028]
-----------------------------
Line 345:
	execl("/bin/sh", "sh", "-c", em->text, NULL);
-----------------------------

It seems that emodule_run(emodule *em) in comm.c
requires the length of PATH shorter than 512 characters,
because of declaration "char envbuf[512];".
The PATH in my .cshrc file was around 400-600 character long.
After I cut a bit of the PATH, then the external modules work fine.
