Messed up my database libraries, help!

[Mark London]

Hi - On redhat 9, I accidently deleted a bunch of files in /lib.  I 
installed the rpms I downloaded from redhat, including db4  However, 
I'm getting the following errors, even though I recompiled cyrus. 
Any suggestions?  I must have messed up the db libraries, but I can't 
figure out how.  Thanks. -  Mark
