Apt-get circular dependencies

Hi!

I have debian sarge installed, but want to use some of the newer mono
packages.
I made source pinning and tried to install some libraries.

Unfortunately, there is a circular dependency:
---
apt-get -f install libpango1.0-0/testing
Reading Package Lists... Done
Building Dependency Tree... Done
Selected version 1.8.2-3 (Debian:testing) for libpango1.0-0
..
libpango1.0-0: Depends: libpango1.0-common (>= 1.8.2-3) but 1.8.1-1 is
to be installed
---

---
apt-get install libpango1.0-common/testing
Reading Package Lists... Done
Building Dependency Tree... Done
Selected version 1.8.2-3 (Debian:testing) for libpango1.0-common
...
libpango1.0-common: Depends: libpango1.0-0 (>= 1.8.2) but 1.8.1-1 is to
be installed
---

How can I resolve this conflict?
Should I force apt-get to install one of these packages?
My experience says, forcing apt-get always results in a package mess.
Therefore, I'm searching for other solutions first ..

Greetings,
Marcus
