Install GDAL python package in virtualenv on mac

I'm trying to instal the GDAL python package, preferably in a virtual environment, but when I try "pip install gdal", I get the following error:

extensions/gdal_wrap.cpp:3085:10: fatal error: 'cpl_port.h' file not found
    #include "cpl_port.h"

I have GDAL version 1.11.4 installed on my Mac. I installed it via Kyngchaos, and it is located at /Library/Frameworks/GDAL.framework/Versions/1.11/Resources/gdal

the cpl_port.h file is located in /Library/Frameworks/GDAL.framework/Versions/1.11/Headers

I've read several related topics but they're all on ubuntu and using older versions of pip that have commands like "--no-install" etc.

Answer

I found the answer on another thread with some minor tweaks:

(Adapted from Yellowcap's answer)

Make a virtual environment:

virtualenv env
source env/bin/activate
cd env

Download the GDAL package version you want, unzip it and cd into it:

pip download GDAL==1.11.2 (or whichever version you want)
tar -zxvf GDAL-1.11.2.tar.gz
cd GDAL-1.11.2

According to Yellowcap, you might need:

export CFLAGS=-Qunused-arguments export CPPFLAGS=-Qunused-arguments

Then:

python setup.py build_ext\
     --gdal-config=/Library/Frameworks/GDAL.framework/Versions/1.11/unix/bin/gdal-config\

     --library-dirs=/Library/Frameworks/GDAL.framework/Versions/1.11/unix/lib/\
     --include-dirs=/Library/Frameworks/GDAL.framework/Versions/1.11/Headers/

Build and install:

python setup.py build
python setup.py install
