I am now able to build QGIS. As far as I can tell, there were two issues affecting the build.

1) Mistakes in my cmake command. I ended up going with:
(Broken up to make it easier to read.)

cmake -D CMAKE_INSTALL_PREFIX=~/Applications \
-D CMAKE_BUILD_TYPE= MinSizeRel \
-D WITH_INTERNAL_SPATIALITE=FALSE \
-D WITH_MAPSERVER=TRUE \
-D SIP_BINARY_PATH=/opt/local/bin/sip-2.7 \
-D CMAKE_OSX_ARCHITECTURES=x86_64 \
-D QWT_LIBRARY=/opt/local/lib/libqwt.dylib \
-D QWT_INCLUDE_DIR=/opt/local/include/qwt \
-D GDAL_INCLUDE_DIR=/opt/local/include \
-D GDAL_LIBRARY=/opt/local/lib/libgdal.dylib ..


2) The portion of the script FindGDAL.cmake script which verifies the GDAL version does not play nice with libraries which are not structured as OS X style frameworks (as is the case for many frameworks installed by MacPorts). To rectify this, I commented out lines 56 through 64 of the script ./cmake/FindGDAL.cmake. 

I suspect I maybe over simplifying or even overlooking something, but wouldn't it make more sense to attempt parsing the output from running
gdal-config --version
rather than grabbing it from a plist file?
