The Pidgin puzzle.

[HermanAA]

If I try to install Pidgin, it says (in Synaptic):

pidgin:
  Depends: libdbus-glib-1-2 (>=0.78) but 0.76-1 is to be installed
  Depends: libgtk2.0-0 (>=2.16.0) but 2.14.4-0ubuntu1 is to be installed
 Depends: libpurple0 but it is not going to be installed
  Depends: perl (>=5.10.0-19ubuntu1) but 5.10.0-11.1ubuntu2.3 is to be
installed

......... so I find them and Mark them (for installation).

Now we get dependencies of dependencies :

libpurple0:
  Depends: libdbus-glib-1-2 (>=0.78) but 0.76-1 is to be installed
  Depends: libnspr4-0d (>=4.7.3-0ubuntu1~) but 4.7.1+1.9-0ubuntu4 is to
be installed
  Depends: libnss3-1d (>=3.12.2~rc1) but 3.12.0.3-0ubuntu5.8.10.1 is to
be installed
  Depends: perl (>=5.10.0-19ubuntu1) but 5.10.0-11.1ubuntu2.3 is to be
installed

If the system knows all this is needed, why is it not installing them?

Do I have the wrong approach to install Pidgin perhaps?
 (are there better ways?)

I did remove the old Pidgin as part of a (non-Synaptic) upgrade.
 Ended up with no Pidgin. 

Now trying to get back on track.

My system:
Ubuntu 8.10 (Intrepid), default.
 Updated.
