• clone github repo or download source release at http://python.org/pypi/pyproj.
• python setup.py build
• python setup.py install (with sudo if necessary).

To use proj4 lib (and data files) that are already installed on the system, set PROJ_DIR environment variable to point to location of proj4 installation before running setup.py. If PROJ_DIR is not set, the bundled proj4 source code and data files are used.

Examples of how to set the PROJ_DIR environment variable:

• Windows - C:\...> set PROJ_DIR=C:\OSGeo4W\
• Linux/OS X on most shells- $ export PROJ_DIR=/lib/

To test, run python -c "import pyproj; pyproj.test()"

For new unit tests, run python unittest/test.py
