New Installation Notes

New Note:
1. When running "paver setup" command, if error about version string parsing occurs, edit ~/.venvs/worldmap/lib/python2.7/site-packages/django/contrib/gis/geos/libgeos.py, search for "ver = geos_version()" under "def geos_version_info()", edit "ver = geos_version()" to "ver = geos_version().split(' ')[0]". In this case the space between the version will be deleted. Finally, run "pave build" again.
2. If File "pavement.py", line 243, in package_dir
package_outdir.mkdir()
AttributeError: 'str' object has no attribute 'mkdir'
Then, go to ~/cga-worldmap/pavement.py, change "package_outdir.mkdir()" to "os.mkdir(package_outdir)".
