pan2 cannot compiled under Yosemite 10.10.1

[FritzS - gmx]

I append my question on
https://trac.macports.org/ticket/41402
too.

Now I have a similar problem, pan2 cannot compiled under Yosemite 10.10.1 and a fresh installation of MacPorts.
Under Homebrew pan2 could not compiled too on another Mac and the newer Xcode Versions.
My Xcode Version 6.1.1

I test this to solve them:
Now I copied an older pan binary (I compiled it under Homebrew and Mountain Lion) from a TimeMachine Backup into the /opt/local/bin/ folder.
If I want start it comes the error: dyld: Library not loaded: /usr/local/lib/libgtk-x11-2.0.0.dylib / Referenced from: /opt/local/bin/pan / Reason: image not found (1005)
but libgtk-x11-2.0.0.dylib is in /opt/local/lib/libgdk-x11-2.0.0.dylib 
What can I do to solve this?
