python w/expat compiled on one box doesn't work on another

[Doug]

I am running solaris 7 on two machines.  I compiled python 2.2.1 with 
expat parser on one machine.  The python binary is located in 
/usr/local/bin and the libraries are located in /usr/local/lib.  I was 
told that if I would tar up the /usr/local/lib/python2.2 directory from 
the one machine.  I could transfer that and the binaries from 
/usr/local/bin to another machine running solaris 7 and all should be 
fine.  Machine 1 acts as a hub for receiving and redirecting soap 
messages between machines on a WAN.  I know that it's parser is working. 
  Machine 2 is supposed to take an input message, parse it and send a 
soap message to Machine 1.  However, I get an error that says that it 
can't find the expat parser.  The environments on the two machines are 
nearly identical (any differences deal with unrelated items).  Can 
someone point me in the right direction as to why it doesn't find the 
expat parser on the other machine.  I can see the expat files in the 
/usr/local/lib/python2.2/xml/parsers directory.

TIA for any assistance.
