[Spacewalk-list] Trouble installing spacewalk on x86_64 centos 5

[Drew]

After successfully installing and configuring Oracle XE server and 
client, I execute "spacewalk-setup --disconnected" and receive the 
following:

[root at owl ~]# spacewalk-setup --disconnected
* Loading answer file: /usr/share/spacewalk/setup/defaults.conf.
* Setting up environment and users.
** GPG: Initializing GPG and importing RHN key.
* Setting up database.
** Database: Setting up database connection.
DB User? spacewalk

Could not connect to the database.  Your connection information may be 
incorrect.  Error: install_driver(Oracle) failed: Can't load

Perhaps a required shared library or dll isn't installed where expected

Appears some sort of mismatch between a 64-bit DBD::Oracle module and a 
32-bit libclntlsh.so.10.1.

So I removed the oracle-instantclient*i386.rpm and installed 
oracle-instantclient*x86_64.rpm. That gives the following error:

[root at owl ~]# spacewalk-setup --disconnected

Different error, but still related to DBD::Oracle. Any suggestions?

Thanks
