Why does the UI look different between the pre-built program and the program built from source?

[greasy]

I recently built Deluge from source myself and this is what the UI looks like:



The version I downloaded from the Deluge website looks pretty different though:



I used PyGTK 2.24.2 when building from source. They are both the same version (1.3.13). How can I make my built version look the same as the released binary?

The top one is Deluge 2.0 develop code not 1.3. Use git branch 1.3-stable.

Also when you build from source the gtk theme is not applied until you package it with bbfreeze
