I strongly suspect its a Fedora problem, not a Freeradius 
problem. (Or else I made a boo-boo configuring the OS)

May or may not be relevant, but I've got two supposedly 
identical Fedora 6 machines, one gets a similar error, the other 
doesn't!.

Both upgraded with yum to current level, followed by manual 
install and configure of Freeradius 1.1.5 - I cut and pasted the 
commands from one machine to the other and I FTPed the files 
including ones I modified. (And the one it works on is the 
SECOND one I installed, so its not a failure to copy correctly!)

I think there must be some difference in my 
/usr/local/lib/libltdl.so.3.1.4 - they are slightly different 
sizes. I have no idea why, I used the same commands to install 
both systems. I will compare them.

Just in case it means anything to anyone I attach the command 
output, but as I said my guess is its a Fedora problem
