software install problems

[Phil Beder <phil@mail.brainlink.com>]

Hello all,
I'm having trouble installing software.  I have downloaded Gimp, Netscape,
Mozilla and others and seem to have compatibility problems with the version
of Debian I'm running.  I thought I had 2.1.1, but in fact it returns Ver
2.0.36 when issued the uname -a command.  

When I tried to install Netscape and Mozilla I got an error message: 
"error loading shared libraries   libgtk-1.2.so.: cannot open shared object
file: No such file or directory"
(I know the libgtk file on my machine is different, probably older)

With Star Office I got:
"wrong glibc version you need 2.1.1"

What do I need to do??
