I tried above approach, results here:

  http://freetexthost.com/u1jyfyyblb

yum is looking for rpm versions that are not in
the 'updates-local' repo, and not in 
the 'base-local' repo! How is yum determining these versions?

  examples: 
    yum wanted: gdb-7.0.1-37.el5.x86_64.rpm, dogtail-0.6.1-4.el5.noarch.rpm
    updates-local has: no dogtail, no gdb
    base-local has earlier versions:
      gdb-7.0.1-32.el5.x86_64.rpm, dogtail-0.6.1-3.el5.noarch.rpm

'updates-local' repo has only about 200 rpms; base-local has
~3200!  So I assume 'base-local' being much larger, should be used
for 'yum groupinstall "Development Tools"'?

Neither repo has a 'repodata/groups.xml' file. 

Pls click on the chopapp.com and freetexthost.com links below to see our
repo tree structure and rpms listing:

  repo "base-local":      http://chopapp.com/#6e1j7alb   
    above is these output of:
      lynx -dump http://172.16.22.8/yum/basepkg               (root of repo)
      lynx -dump http://172.16.22.8/yum/basepkg/repodata
      lynx -dump http://172.16.22.8/yum/basepkg/iso
      lynx -dump http://172.16.22.8/yum/basepkg/iso/Server    (rpms)

      I don't think there is a comps.xml below 'yum/basepkg'.

  repo "updates-local":   
    http://freetexthost.com/sr11fkny32    ( far fewer rpms, about 10% of base!? )

      Notice 'comps.xml' is at root of updates-local repo.

Since yum was looking for versions of gdb and dogtail that neither of our local repos had
do I need to ask our sys admin to get us access to a more up to date
local repo base and updates repo?  Specifically what should I ask for; what do
we have a reasonable right to expect for local repos?

>From 'man createrepo':

  EXAMPLES
    Here is an example of a repository with a groups file. Note
    that the groups file should be in the same directory as the
    rpm packages (i.e. /path/to/rpms/comps.xml).

    createrepo -g comps.xml /path/to/rpms

So, before there is any hope that 'yum grouplist' will work,
my hunch is that I should ask our sys admin to re-run createrepo
on the "base-local" repo server in this way:

   cp /path/to/comps.xml /var/www/html/yum/basepkg/iso/Server
     # rpms are in       /var/www/html/yum/basepkg/iso/Server
     # Where will he get this comps.xml ( w/'Development Tools' & others )?
   cd /var/www/html/yum/basepkg
     # this is root dir of repo, having ./repodata as a subdir
   createrepo -g iso/Server/comps.xml -o . iso/Server
     # "-o ." so ./repodata is used 
     # instead of /var/www/html/yum/basepkg/iso/Server/repodata

What if 'iso/' above is a RO filesystem?  Can comps.xml be written
anywhere, as long as the arg to "-g" gives the full pathname to it?

Where will the admin find the official/correct comps.xml?  
Perhaps the iso/ dir is a DVD or CDROM?:

Unfortunately, there is just 1 subdir above: 'Server/', and all it has
are rpms (no comps.xml).

thanks for any help, comments, corrections etc,

Basic question: Is the directory that contains "./repodata" considered
the root of the repo, ie is "./repodata" a top level subdir of the
repo URL?
