Thanks Mark.

The above helps some, but I am not exactly sure how to proceed yet.

1)Does the build of the Omni Project build the libomni.so library(a 
shared library I presume)? The library is not currently resident on my 
system, so I got to build it somehow. The library missing could be my 
problem. I created dummy libomni.so's in /lib and /usr/lib to see if I 
would get a different error, but I get the same error, indicating(maybe) 
that I need the fixes which are in CVS and the tarball on the omni 
download site?
2)The Omni function compiled into espgs is just an interface to the 
libomni.so library?
3)Our system, in general does not use the CVS's for standard 
installation, but rather source(not binary or rpm's)tarballs. I don't 
know how to use a CVS in any case(guess I could learn tho).
4)You say the latest CVS for both projects has the latest fix you 
alluded to, so I presume the fixes will show up in espgs 7.05.6 or later?

Can you help any here Jason(Jason is our printer guru in SourceMage)?

Thanks,
