Currently wxgtk2.8-2.8.12-4 is blocked from building on 10.9 with the fink from the Futureproof branch. A 'Distribution: 10.7, 10.8" field was added to libpng15, libjpeg8 and libtiff as a nudge to migrate packages to a unified set of graphic libraries based on libpng16, libjpeg9 and libtiff5. Note that the driver behind this is the incompatible ABI changes between libjpeg8 and libjpeg9 although the same general apply to any shared library that might have subtle changes to its data structures and calls between different soversions.
The attached info file (which uses the current patch) implements the necessary BuildDepends and Depends changes...
