[CentOS] centos 4.2 (32bit) app installed on (64 bit) box mising library

I have a centos 4.2 32bit app that when installed on centos 4.2 64 bit
box and try to run it I get "libxml2.so.2 not found".

however if I "rpm -qa | grep libxml2" it shows up just fine.

How can I get this app to run on the 64bit box (without recompiling yet).
The recompiling will come someday...
right now I just would like it to run.

Thanks

Jerry
