Although in Sitepackages, not importable

I installed basemap the following:

Download the source from here:

```
http://sourceforge.net/projects/matplotlib/files/matplotlib-toolkits/
```

Follow the instructions:

```
cd geos-3.3.3
export GEOS_DIR=/usr/local
./configure --prefix=$GEOS_DIR
make; make install
```

Then I went on the PROJ4 website http://trac.osgeo.org/proj/
Downloaded vers 4.9.1

```
./configure
make
make install
```

Then back into the basemap folder:

```
sudo python setup.py install
```

No error messages during that process.
However,

```
from mpl_toolkits.basemap import Basemap yields
"No module named basemap"
```

I checked my python 2.7 folder under

```
/Library/Python/2.7
```

There is folder "mpl_toolkits" which contains a folder basemap.
Why is it not importing?

Reproduce the reported `from mpl_toolkits.basemap import Basemap` failure using the installation commands and Python 2.7 path shown in the issue. Inspect `/Library/Python/2.7/mpl_toolkits/basemap` and the active interpreter's import path; done means identifying why the installed package is not importable and documenting a verified fix.
