Hi Tom,

Sure likes like you don't have yacc.  FYI, yacc is a parser generator. 
In the ldm it's used to parse entries in the configuration files. 
Here's what's on my machine:

[anne@localhost anne]$ locate yacc
/usr/bin/byacc
/usr/bin/yacc
/usr/share/doc/vim-common-6.0/syntax/ayacc.vim
/usr/share/doc/vim-common-6.0/syntax/yacc.vim
/usr/share/doc/ruby-docs-1.6.4/doc-en/yacc.html
/usr/share/doc/ruby-docs-1.6.4/doc-ja/yacc.html
/usr/share/doc/ruby-1.6.4/sample/exyacc.rb
/usr/share/doc/kdelibs-devel-2.2.2/kio/yacc_h.html
/usr/share/man/man1/byacc.1.gz
/usr/share/man/man1/yacc.1.gz
/usr/share/vim/vim60/indent/yacc.vim
/usr/share/vim/vim60/syntax/ayacc.vim
/usr/share/vim/vim60/syntax/yacc.vim
/usr/share/a2ps/sheets/yacc.ssh
 

At the Redhat site I see byacc listed as a package for 7.1 and 7.3 and
you can see it's also on my 7.2 machine.  It's probably available from
Redhat for 7.2 too, I just haven't come across it in my brief search. 
Do you have the disk available from which the OS was installed?  I bet
it's on there.  Or, probably bison, from the gnu site, would also work.

Were there any messages in the log?  At that point I would try to run
pqcreate directly from the command line in verbose or debug mode, which
may give you more information about any problems.  Will 'kill -9' kill
the process?

Offhand I don't think there would be a problem.  The fully qualified
name in ldmadmin is used mainly for sending statistics to us.   If this
is an internal machine maybe you don't even want to run pqbinstats 
(although please do so on your IDD machine because those are important
to us).

Regarding hostnames, the most important aspect for the ldm is that a
machine can do both a forward and reverse lookup.  So if your name
service is set up so that the hostname sans domain is resolvable to an
IP address and vice versa, it should work fine.  If that's a problem,
you can use the IP address in ldmd.conf, and the forward and reverse
lookup will be bypassed.

They don't seem convoluted to me!  You're welcome.  Please let me know
how things turn out.
