Dependency problem on installing libgtk2.0-dev

[Removed by request]

I'm using Ubuntu 14.10 dev and on installing libgtk2.0-dev I'm getting the following output:

sworddragon@ubuntu:~$ sudo apt-get install libgtk2.0-dev

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libgtk2.0-dev : Depends: libpango1.0-dev (>= 1.20) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Thank you for your bug report, what happens if you try to install libpango1.0-dev? What sources do you have enabled?

Hm, somehow I have newer packages than the current existing ones:

root@ubuntu:~# apt-cache policy libpango-1.0-0
libpango-1.0-0:
  Installed: 1.36.3-1ubuntu1.1
  Candidate: 1.36.3-1ubuntu1.1
  Version table:
 *** 1.36.3-1ubuntu1.1 0
        100 /var/lib/dpkg/status
     1.36.3-1ubuntu1 0
        500 http://archive.ubuntu.com/ubuntu/ devel/main amd64 Packages

On checking for all packages:

root@ubuntu:~# clean --check-obsolete
Found the 3 following obsolete packages for all versions: wine1.7-amd64:amd64 wine1.7-i386:i386 wine1.7:amd64
Found the 7 following obsolete packages for the current version: gir1.2-pango-1.0:amd64 libglib2.0-data:amd64 libpango-1.0-0:amd64 libpango1.0-0:amd64 libpangocairo-1.0-0:amd64 libpangoft2-1.0-0:amd64 libpangoxft-1.0-0:amd64

After downgrading these packages libgtk2.0-dev doesn't shown any dependency issues anymore.
