James,

We have at least one site running the LDM 5.1.x under RH 8 (NIU), and
they are not having problems with ldmadmin.

To get this listing, you would have had to edit ~ldm/bin/ldmadmin to set
$data_path.  The default for this is:

$data_path = "$ldmhome/data";

Give this, I am curious to know what would happen if you:

o created a link from ~ldm/data to /data/ldm:

  <login as 'ldm'>
  cd ~ldm
  ln -s /data/ldm data

o edited ~ldm/bin/ldmadmin and return $data_path to its original setting
  (show above)

I don't think that this should fix anything, but I am curious to see if
it does.

The error you included above is from Perl, so we have to suspect your
Perl version.  What does the following give:

% perl -version

It is like you have a Perl problem of some sort, but the question is what?

>Thank you in advance.
