I could not determine why slon compiled with 7.3.10 had communcation problems, 
but I was able to get test 1 to complete by using the slon that was compiled 
against 8.0.5.

This jogs my memory... I believe I did the same when I initially used slony to 
upgrade from 7.3 to 7.4.  While I would feel uncertain using this 
configuration permanently, it should suffice for upgrade purposes.  As I 
understand it, Postgresql 7.3 is no longer supported anyways.
