py-cartopy @0.15.1: Proj4 4.9.0 must be installed

[Chergnat]

Hello,

The installation py-cartopy failed because the file wkt.pyc could not be read during execution.

I am using OS X El Capitan, 10.11.6 and Xcode 8.2.1.

I have tried to clean and reiterate the install, but not to avail.

I have checked that the file wkt.pyc did indeed exist. Here is the output of the ls -alt command:

-rw-r--r--  1 root  wheel  1626 Jan 29 08:07 /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/shapely/wkt.pyc

I am joining the py27-cartopy/main.log for details. Here is the most relevant excerpt:

Some help would be greatly appreciated.
