Capistrano just hangs.

I can deploy successfully to one set of servers, but not the other.
Both the deployment server and the target servers (application on one,
DB on the other) that work are running openSuSE on a 32 bit processor.
 The servers that I cannot deploy to are running Enterprise SuSE 10.1
on a 64 bit machine.  I can deploy manually (checkout) on the servers
that do not work with Capistrano.  All machines have the same root
password.  I serve subversion using Apache from an openSuSE machine
with a 32 bit processor.  All  machines are virtual Zen machines.

You appear to have all necessary dependencies installed

I'd appreciate any suggestions.
