SciLinux6 perl Test::Trap and Tk installation…how

A more or less fresh install of SciLinux 6:

[CODE] $ cat /etc/redhat-release Scientific Linux release 6.0 (Carbon) $ uname -an Linux bigbox.em.local 2.6.32-131.6.1.el6.x86_64 #1 SMP Tue Jul 12 17:14:50 CDT 2011 x86_64 x86_64 x86_64 GNU/Linux
[/CODE]

I'm trying to install a great little package called ClusterSSH:

http://sourceforge.net/apps/mediawiki/clusterssh/index.php?title=Main_Page

http://search.cpan.org/~duncs/App-ClusterSSH-4.00_06/bin/ctel

Apparently EL6 yum keeps wanting to install perl modules from EL5.5, so, from:

scilinux6 (rhel6) perl pathing question

have to do something different than I've gotten used to doing, namely:

# yum install 'perl(something::something)'

So, here's the problem:

# perl Build.PL
Checking whether your kit is complete...
Looks good

Checking prerequisites...
 - ERROR: Test::Trap is not installed
 - ERROR: Tk is not installed

ERRORS/WARNINGS FOUND IN PREREQUISITES.  You may wish to  install the versions

of the modules indicated above before proceeding with this installation

# rpm -qa |grep Tk

note the el5 suffix…grrr

# sudo yum install 'perl(Tk)'

# sudo yum install 'perl(Perl::Tk)'

So what do I do now?

Thanks in advance!
