dpkg problems

["T.V.Gnanasekaran" <gnana@lanminds.com>]

Hi,

I am new to debian.

I recently compiled and upgraded gtk.
After that, whenever I install any package using apt-get it says:

# apt-get install xfstt
Reading Package Lists... Done
Building Dependency Tree... Done
You might want to run `apt-get -f install' to correct these:
Sorry, but the following packages have unmet dependencies:
  libgtk1.2: Depends: libglib1.2 (>= 1.2.0) but it is not installable
             Depends: xlib6g (>= 3.3.4-0slink1) but 3.3.2.3a-11 is
installed
  libgtk1.2-dev: Depends: libglib1.2-dev but it is not installable
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or
specify a solution).

what is this problem? how do I 'fix' it?
