This looks like you were trying to define $hostname to be 
'weather3.admin.niu.edu' but forgot to comment out the line before it
and uncomment out itself.  The lines should read:

# chop($hostname = `uname -n`);
$hostname = "weather3.admin.niu.edu";

Do you want your queue size different from 400 MB?  If yes, you
musth change $pq_size here.

Also, since the strategy of the new distribution is to build with large
file support, you will need to delete and remake your queue _if_
you use the default build.  This is explained in the installation
instructions.

Please note that the last line is commented out.

I think that you should:

- check the output of a 'uname -n'.  If it returns a fully qualified
  hostname, you do not need to modify $hostname in ~ldm/etc/ldmadmin-pl.conf

- undo your mod to the 'require' line

>Help!

Please let me know if the above doesn't get you going.
