Failed install of freeradius2-2.1.6-2.el5.i386

[Steven Sprague]

Today I tried to install freeradius2-2.1.6-2.el5.i386 and ran into a
dependencies problem I could not solve. After downloading support for
SQL and all required dependencies I started my install and got this
message - Missing libltdl.so.3.

I am running Linux rhel 2.6.18-8.el5 and wonder now where on my software
disks (I have searched) is this file? 

Is this file part of some other software required to run
freeradius2-2.1.6-2.el5.i386?

Suggestions ?

Thanks

Steven
