While building SUMO (Simulation of Urban MObility http://sumo.sf.net/) in mac os x (10.6.8) the following error occured. I don’t think this is specific to SUMO, rather python installation in mac related issue, so I am posting here. FYI, the python version is 2.7.1 here.

Any idea on how to solve this issue?

I found a link on SUMO’s website (here):

 export CPPFLAGS="$CPPFLAGS -I/opt/local/include"
 export LDFLAGS="$LDFLAGS -L/opt/local/lib -lpython2.7"
./configure --with-fox=/opt/local --with-proj-gdal=/opt/local --with-xerces=/opt/local --prefix=/opt/sumo --with-python

It worked for me to get past this compilation error. These lines are working with MacPort though.
