Description
Trying to run mapnik-python against macport installed mapnik library leads to the following error
RuntimeError: Cannot initialize proj_transform for given projections without proj4 support (-DMAPNIK_USE_PROJ4): '+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs'->'+proj=lcc +ellps=GRS80 +lat_0=49 +lon_0=-95 +lat+1=49 +lat_2=77 +datum=NAD83 +units=m +no_defs'
mapnik-config --cflags --cxxflags return the following

In appears that mapnik is not compiled wint proj4 supports and there is no variants for enabling this.
Please could you add MAPNIK_USE_PROJ4 supports as variant ?
Thanks.

It appears the PROJ option is enabled by default in mapnik build configuration but the proj library is not able to find it:
... Checking for C library proj... no ...

I have found that the Portfile define the wrong path for PROJ_INCLUDES and PROJ_LIBS since proj4 and proj (proj5) are in their respecctive install directory.
see https://github.com/macports/macports-ports/blob/master/gis/mapnik/Portfile#L111

proj4 is in the dependancies but it is not apparently getting used.
