06. 10. 2008 Test user feedback

In the week of Oct 6th we are working with test users to get the user environment production ready.

Feedback from FredericRonga:

ROOT error
(Maybe because the system libraries are in 64 bits, but CMS software (including ROOT) is in 32 bits?)
```
> root -l PATLayer1_Output.fromScratch_fast.root
root: error while loading shared libraries: libXpm.so.4: cannot open shared object file: No such file or directory
```
DerekFeichtinger: I installed xorg-x11-devel.i386 and other i386 architecture dependencies on the UI.

can't get a Kerberos ticket (for CVS checkout)

> cvs co -rCMSSW_1_6_12 PhysicsTools/PatAlgos
cvs [checkout aborted]: kerberos authentication failed: You have no tickets cached
> kinit
kinit(v5): Client not found in Kerberos database while getting initial credentials

DerekFeichtinger: I added the CERN.CH realm to the /etc/krb5.conf file on the UI. Users can now get tickets from PSI and CERN realms. Please test.

need to source $VO_CMS_SW_DIR/cmsset_default.csh (see here)
DerekFeichtinger: This was actually decided on purpose. I wanted to provide the possibility for users to run without a CMS environment if they want. The automatic sourcing was activated for some time, but I decided against it. Should we activate it again?
