Did you work your way through:

Preinstallation Requirements
http://www.unidata.ucar.edu/packages/ldm/ldmPreInstallList.html

In particular, did you:

Configuring the Operating System as root

     Add the following lines to file /etc/services 

                 ldm 388/udp unidata        # UCAR Unidata LDM
                 ldm 388/tcp unidata        # UCAR Unidata LDM
            

     This allows programs such as netstat to associate activity on IP port 388
     with the LDM.

     Add the following line to file /etc/rpc 

                 ldmd 300029 ldm
            

     This allows programs such as rpcinfo to identify RPC program number
     300029 as the LDM.

     The LDM uses the system logging daemon, syslogd, to write error
     messages by the local0 facility. 

         Add the following entries to file /etc/syslog.conf 

                local0.debug       /usr/local/ldm/logs/ldmd.log
                

         Modify the following lines in file /etc/syslog.conf so that LDM
         messages will not be written to the console 

         *.err;kern.notice;auth.notice;user.none;local0.none     /dev/console
         *.err;kern.debug;daemon.notice;mail.crit;user.none;local0.none  
/var/adm/messages

     Create the user account called 'ldm' (see below)

     By convention, the LDM home directory should be /usr/local/ldm or
     /home/ldm. If /home/ldm is used then a link needs to be made from
     /usr/local/ldm to /home/ldm, ie 

             % cd $HOME
             % ln -s $HOME /usr/local/ldm


If the answer is yes, the next question is whether or not you remembered to
set the setuid bits on rpc.ldmd and hupsyslog?

Make rpc.ldmd and hupsyslog suid root

     Change permissions for rpc.ldmd and hupsyslog to be setuid root. This step 
needs to be done as root 

             % cd ~ldm/{version-directory}/bin
             % chown root rpc.ldmd
             % chown root hupsyslog
             % chmod u+srwx,g+rx,o+rx rpc.ldmd
             % chmod u+srwx,g+rx,o+rx hupsyslog
            

>Also, I've compared the installation side by side with

>permissions or links and found no problems that way.

OK, I am betting that the first step(s) were not done/done correctly.
The reason for this is that rpc.ldmd is complaining about not being
able to 'register service 300029 5 tcp 388'.

I would go back and start at the web link I list above and work my way
through each step.

I can't explain the non-inheriting of environment when specifying 'su - ldm'.
I can say that tcsh is OK to use.

No, the 5 is not an error code.

You might also try looking through the searchable online documentation

Searchable LDM Web Documents
http://www.unidata.ucar.edu/glimpsedocs/ghldmdocs.html

The following found using 'rpcinfo' as  asearch key looks promising:

Unidata LDM Workshop: LDM and IDD Troubleshooting
http://www.unidata.ucar.edu/packages/ldm/ws/ldm_trouble-pr.html

The next place to look is:

Searchable archives of LDM support 
http://www.unidata.ucar.edu/glimpsedocs/ghldm.html

and

Searchable archives of ldm-users 
http://www.unidata.ucar.edu/glimpsedocs/ghldm-users.html

Use 'rpcinfo', '300029', and/or 'registered' as search keys and see
what others have asked and have been answered on this subject.  It is
most likely that the problem you are seeing has been run into by
someone else in the past and has been resolved.  Our online email
archives are very good for reviewing all of the transactions we have
had with sites in the past.

re: check setting root permission on rpc.ldmd and hupsyslog
