I am a long-time mandrake user...trying to convert over to Debian.  

I just got Ximian-Gnome installed, but now when I do an apt-get upgrade I
am getting errors about unmet dependancies.  I would appreciate it if
someone could help point me in the right direction to fix this.  I could
fix this with RPM's but I don't know enough about Debian's packaging
format to know how to fix this yet.

When I apt-get upgrade I get the following:
  merlin:/home/dave# apt-get upgrade
  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:
    libguile6-slib: Depends: libguile6 (= 1:1.3.4-helix5) but 1:1.3.4-3 is
  installed
  E: Unmet dependencies. Try using -f.

When I add the -f parameter it errors out with:
  <...snipped...>
