$LDMHOME should be the same as ~ldm, which is usually /usr/local/ldm.

~ldm/bin is a link to ~ldm/runtime/bin, and in your case, runtime should
point to ldm-5.1.2.  So, ultimately ~ldm/bin is a link to
~ldm/{version-directory}/bin.  We use the link 'runtime' so that new
versions of the ldm can be installed while the old one is still running,
then when you want to change versions usually all you must do is stop
the ldm and change the link.  (Some versions require a new queue to be
made.)

Btw, I forgot to mention one other essential logging piece.  The file
~ldm/logs/ldmd.log must exist.  See
http://www.unidata.ucar.edu/packages/ldm/ldmBinaryInstallList.html and
look under "Change the runtime link", "For a new LDM installation",
specifically, "Create the LDM log file".  This command will create a 0
length log file.

So, no - with the runtime link described above no executables need to be
copied.

For a first time installation it is necessary to copy files into
~ldm/etc.  For subsequent upgrades, you just keep your own versions of
those files across upgrades.  These are configuration files that you
will tailor for your site.  This is why the etc directory is *not* a
link, unlike the bin directory, for example, which is a link to
runtime/bin.

You need to add the ldm executables to your path.  See
http://www.unidata.ucar.edu/packages/ldm/ldmPreInstallList.html,
specifically the section called "The User 'ldm' Account"

No need to apologize!  You're welcome.
