[CentOS] centos5 - yum groupinstall and yum grouplist

If I do a minimal centos 5 install

Then if I do a

yum -y update

then if I do a

yum groupinstall "Development Tools" "Development Libraries"

(is that syntax right, it works)?

both are installed yet if I

yum grouplist

this is all that shows up as installed even though both are installed

Installed Groups: Development Libraries System Tools Dialup Networking Support Network Servers Mail Server

If I check to see if I can install them individually after that they both say there are installed and up to date.

:-)

Just wondering if it was something that needs to be addressed as a minor inconvenience or pretty output type bug

thanks
