Log Message:
Update to 1.9.4 (leaf).

This required a fairly massive rototill of the PKGNAME/DISTNAME
because of bugs in upstream distfile generation, reported at
https://github.com/jswhit/pyproj/issues/7
But there are no signficant changes in packaging other than coping with the
distfile naming bug.

1.9.4 (git tag v1.9.4rel)
 * migrate to github from googlecode.
 * update proj4 source code from svn r2595 (version 4.9.0RC2).
 * include runtime_library_dirs in setup-proj.py.
 * added to_latlong method (issue 51).
 * fix back azimuth when lon1 and lon2 are identical.
