[OzTeX] eps files not previewing properly

[Ken Pierce]

Thanks, Andrew,

There's something still not right:

/usr/local/bin/gs

ken-pierces-computer:~%ls -l /usr/local/bin/gs
lrwxr-xr-x  1 root  admin  21 18 Jan 15:04 /usr/local/bin/gs ->

unix_path=:usr/local/bin:/usr/local/teTeX/bin/powerpc-apple-darwin-current:/bin:/sbin:/usr/bin:/usr/sbin:/usr/X11R6/bin

setting convert_eps to 3 didn't help.

But here's something that works: You'll recall that I had been using 
the fink installation of tetex and gs.  If I revert to the (earlier) 
fink version, and add the appropriate path to my "unix_path", then 
OzTeX can call gs and create the preview image without difficulty. 
So this is an obvious workaround; on the other hand, you've advised 
me to use Gerben Wierda's versions, which makes sense.

Further thoughts?
