Configure options I use to compile for Snow Python 2.6:

export MACOSX_DEPLOYMENT_TARGET=10.6
export DESTDIR=~/Applications/qgis-release
export CFLAGS="-isysroot /Developer/SDKs/MacOSX10.6.sdk"
export CXXFLAGS="-isysroot /Developer/SDKs/MacOSX10.6.sdk"
export LDFLAGS="-isysroot /Developer/SDKs/MacOSX10.6.sdk"

cmake ... \
-D CMAKE_OSX_DEPLOYMENT_TARGET="10.6" \
-D CMAKE_OSX_SYSROOT="/Developer/SDKs/MacOSX10.6.sdk" \
-D PYTHON_EXECUTABLE=/usr/bin/python2.6 \
-D SIP_BINARY_PATH=/Users/Shared/unix/python-snow/bin/sip \
...

Any external dependencies (like the QScintilla2 you added, and Qwt, spatialindex, ...) must be also compiled with the 10.6 deployment target.  My frameworks are OK.  The sip bit above assumes a separate SIP/PyQt compiled for 10.6 in the system Python 2.6 site-packages.  But compiling SIP/PyQt *for* Snow Python 2.6 *on* Lion is tricky, and needs a hack to the system Python.  (the simple solution is to compile on Snow)
