---------------------------------------+------------------------------------
 py26-matplotlib-basemap does not build when installed in a non-standard
 location (i.e., other than in /opt/local). The reason for this is that, by
 default, the setup script for basemap only looks for the GEOS library in a
 predefined set of locations. This check occurs at build time and at
 install (destroot phase) time.

 However, this installation also looks for the GEOS_DIR environment
 variable when looking for the GEOS library.

 Attached is debug output showing the error (build_output.txt) and a patch
 to the Portfile, adding the environment variable GEOS_DIR (set to
 ${prefix}) in both the build and destroot phases.
