[plug] package installation

[Jon L.Miller]

I was trying to install a package in rh72 and got an message that stated that 
several files from the install package conflicts with the file of another 
package that is associated with an already installed package.  My question is 
do I:
1) uninstall the already installed package or
2) use and -U in the rpm  command to upgrade, although this has been tried 
and it does nothing.
3) force the installation

The package in question si the cups-1.1.4-linux-2.2.14-intel.rpm and the 
conflicting files are:
file /usr/bin/cancel from install of cups-1.1.4-1 conflicts with file from 
package LPRng-3.7.4-28
file /usr/bin/lp from install of cups-1.1.4-1 conflicts with file from 
package LPRng-3.7.4-28
file /usr/bin/lpq from install of cups-1.1.4-1 conflicts with file from 
package
LPRng-3.7.4-28
file /usr/bin/lpr from install of cups-1.1.4-1 conflicts with file from 
package
LPRng-3.7.4-28
file /usr/bin/lprm from install of cups-1.1.4-1 conflicts with file from 
package LPRng-3.7.4-28
file /usr/bin/lpstat from install of cups-1.1.4-1 conflicts with file from 
package LPRng-3.7.4-28
file /usr/sbin/lpc from install of cups-1.1.4-1 conflicts with file from 
package LPRng-3.7.4-28

I used both rpm -ivh cups.... and rpm -Uvh cups....

TIA
