Hi Martin,

First questions:

- presumably, you copied the binaries into a directory that is in the
  PATH for the user running the LDM on the new machine.

  Is this true?

- after copying the binaries, did you verify that they will run successfully
  on the new machine?

  What I have in mind is using the *nix 'ldd' facility to verify that all
  shared libraries needed by the executables are available on the new
  machine.  Here is an example:

  <as 'ldm'>

  -- assuming that the GEMPAK GRIB decoder 'dcgrib2' was copied to the
     ~ldm/decoders directory AND this directory is in the PATH of the
     user 'ldm' AND this file is set to be executable, run:

     ldd ~ldm/decoders/dcgrib2

     What are the results?

- what version of the LDM iss running on your "old" machine?

What does the following look like:

ls -alt ~ldm/var

Cheers,

Tom
