It may be the gdal-config path creating confusion.  There are actually 2 version of gdal-config in my framework.  The one you used that is in the unix/ folder is designed for old software that doesn't handle framework flags - it uses the standard -Lpath -llib form.  Maybe the test for the GDAL functions is seeing the Macports GDAL first, which causes a confusion of GDAL and tiff/geotiff libs.

The gdal-config in the Programs folder is what you want - it uses -framework linking, so you don't accidentally get a non-frameword GDAL.  Same goes for manually specifying the GDAL lib and include paths. So:

-D GDAL_CONFIG=/Library/Frameworks/GDAL.framework/Programs/gdal-config
-D GDAL_INCLUDE_DIR=/Library/Frameworks/GDAL.framework/Headers
-D GDAL_LIBRARY=/Library/Frameworks/GDAL.framework

(cmake knows that a .framework for a library is a framework, and how to translate that for compilation)
