Hello,
while updating Basemap package in Debian, I noticed that
lib/mpl_toolkits/basemap/pyproj.py could use the same BASEMAPDATA
variable handling as of lib/mpl_toolkits/basemap/__init__.py , so I'm
applying a patch like this:
Index: basemap-1.0.5+dfsg/lib/mpl_toolkits/basemap/pyproj.py

Maybe you can consider applying it upstream too (except for the part
of setting it to '/usr/share/basemap/data' in case no variable is
passed, it's a Debian specific change).
