Starting to change readme for osx buidling
Ignore some osx files
Adding osx makefile in /build, depending on macports install
Changing to boost 1_55 and using filesystem3, using __APPLE__ macros this time, should be changed to boost version of course ;)
Adding a apple macro here, but basically it depends on boost version
Oh, this should be a MACRO
Oh my, not that clean, still mixing up osx and boost version
Fixing more boost filesystem 2 vs. 3
Cleaning mapnik python bindings
Cleaning for linux
