I have been doing `gpend; cleanup -c` after each test.

I had not discovered these commands yet. I will look into them right
away and see what they turn up.

I apologize if I am overlooking something simple, but I am not sure what
script you removed. I did a find on gpclear and all I found was the
binary and related documentation.

I followed the link you provided and I noticed when I ran the sfmap
example that I too had "[GEMPLT -101]  NOPROC - Nonexistent executable".
I just hadn't noticed it before. The link you provided says that the
error is due to the program not being able to talk to gplt. However,
when I run `ls $GEMEXE/gplt` it returns information about gplt. So I
don't think the path is screwy. It may indeed not be seen, but I don't
known if it is the path. Every time I check the path it returns the
'right' information. 'Right' being at least what I *think* it should be;
I am using the information I found online as well as Michael's paths
below as guidelines for how my paths should line up.
