[LDM #FPM-496740]: gempak decoders failing

Dave,

An exit status of 127 is unusual. I suspect that the pqact(1) process is able 
to successfully hand the program over to the operating system to be executed 
but that the operating system is unable to execute it for some reason.

It could be that the ld.so utility is unable to locate the necessary dynamic 
libraries. As the LDM user, what are the outputs of the commands
    ldd /home/gempak/GEMPAK7/os/linux64/bin/dctaf
    ldd /home/gempak/GEMPAK7/os/linux64/bin/dcgrib2

> I updated my LDM to 6.13.4, and my gempak to 7.3.0.  I am getting
> 'Deleting failed PIPE' errors for  my gempak decoders.  I saw a similar
> errors in the support archive number LDM #RQD-888533 but none of the
> steps in that ticket helped.  A snippet from ldmadmin tail is shown below:
