I've had a problem like this with yum when I installed a copy of Brightmail and Sun Messaging Server on 
the machine and ldconfig path was changed to include those directories "before" /usr/lib. 

1) ldd the binary and make sure all the correct libs are being used
2) Run yum under gdb and send us the backtrace
3) As someone pointed, send/post the log from: strace yum update
