[Yum] 'yum groupinstall <foo>' does not install packages

[Michael J. Carter]

I've created a local group using yumgroups.pl that the yum client sees:

[root at hannah root]# yum grouplist
Setting up Group Process
Setting up Repo:  rhel3-isr-extras
repomd.xml                100% |=========================| 1.1 kB   
00:00
Available Groups:
   rhel3-isr-extras
Done

This group has some packages that aren't currently installed:

[root at hannah root]# yum list

Installed Packages

zsh.i386                                 4.0.7-1                installed
Available Packages
RealPlayer.i586                          10.0.1.436-20040924    rhel3-isr-extras
TIVguid.i386                             1.1.0-0                rhel3-isr-extras
TIVsm-API.i386                           5.1.5-0                rhel3-isr-extras
TIVsm-BA.i386                            5.1.5-0                rhel3-isr-extras

But the uninstalled packages won't install as a group:

[root at hannah root]# yum groupinstall rhel3-isr-extras
Setting up Group Process
Setting up Repo:  rhel3-isr-extras
repomd.xml                100% |=========================| 1.1 kB    00:00
Reading repository metadata in from local files
rhel3-isr-: ################################################## 52/52
No packages in any requested group available to install

Any idea what might be wrong?

TIA,
mjc
