I'm puzzled by this as well. I would expect the -I/sw/include to be 
sufficient.

A difference between core/Makefile.am and projectionselector/Makefile.am 
is that libqgis_core_la_CXXFLAGS contains $(GEOS_CFLAGS) and 
libqgsprojectionselector_la_CXXFLAGS doesn't. An extra -I/sw/include 
from $(GEOS_CFLAGS) should be redundant but perhaps it's needed.

Another idea is to add -v which should echo the actual include path 
assembled from all the options. This may provide some insight to the 
failed search.

Although I first used fink, and later darwin-ports, when I wasn't very 
familiar with *nix, I did have to struggle with obscure path issues. 
After becoming more familiar with the *nix directory structure and build 
tools, I eventually found it simpler to directly install all additions 
or Apple-overrides into /usr/local.
