yum install <dependency> (more than 1??)

[SlickUSA]

I am trying to install a backup client and i get lots of dependency messages:

 rpm -U gskcrypt64-8.0.14.11.linux.x86_64.rpm
error: Failed dependencies:
        libc.so.6()(64bit) is needed by gskcrypt64-8.0-14.11.x86_64
        libc.so.6(GLIBC_2.2.5)(64bit) is needed by gskcrypt64-8.0-14.11.x86_64

I am not very good when it comes to Linux, especially dependencies, but i tried every variation i could think of:

yum install libc*
Setting up Install Process
Setting up repositories
Reading repository metadata in from local files
Excluding Packages from Amcom-RHEL4 - Updates
Finished
Parsing package install arguments
No Match for argument: libc*
Nothing to do

What can i try to do next at this point? I don't really know much about this server since it isn't a project i am involved with, i just know they want its data backed up. I have a feeling that there are a lot more dependencies that will show up as i do the other 3 rpm files for this package....

You can use wildcards with yum, but you have to enclose the expression in single quotes, as in: yum install '*libc*'

In any case, you generally should not use RPM to install packages on versions of RHEL that support yum as it will not install the missing dependencies for you, whereas yum will. I only use RPM to install packages in cases where I need a newer version of a package than the distribution supports, and it is safe to either install over the other version, or can be installed along with the other version. I had to do that recently on my RHEL 6.2 clone in order to get the ffmpeg package to update.
