I often have problems installing programs because I don't have all the libraries like the once below. Where am I able to get all these libraries? Whats the easiest way to get around this? Why do I often get this problem?

[root@localhost src]# rpm -Uvh perl-Tk-804.027-3.2.el4.rf.x86_64.rpm

What distro are you using? Most have some kind of package manager that can figure out what dependencies are needed and install them from some online repository. To give you more help we need to know what you're using.

I use centos 4.5

you can use yum,

http://sial.org/howto/yum/

there are a lot of programs that yum will not install

including perl tk

when doing yum list | grep perl-Tk
no results are found

perl tk is also not found

did anyone have this problem before?

If the package isn't in the yum repositories you'll have to track its dependencies down by hand, unfortunately. In this case it looks like it needs 64 bit versions of some fairly common libraries. Are you running a 64 bit distribution? If not installing an x86_64 RPM is not going to work at all. What worries me is that it looks like the RPM is looking for both current and old versions of the C library (libc). Your system won't function without some sort of glibc installed, so this is a bit puzzling.

Can you post back and say whether or not you're running on an x86-64 machine? If so can you you do "rpm -qa | grep glibc"?

No, I am running a 32 bit system. That explains my problem. Sometimes I do install other software where I will be missing just 1 or 2 libraries. How do I track those down?

I have usually been able to find missing libraries by simply typing the full name in a Google search.
