can't install reportlab mac OS X 10.9.2 + python2.7

Question

I'm struggling to install reportlab on mac OS X 10.9.2 with python 2.7. I managed to install it using pip3 even if I need it for python2.7 so I believe I have all the required packages installed.

Can you please help?

Here is the install log (If you need the full unstripped log, just ask):

Just found out the solution here. Just add these env settings prior to compilation to tell clang to ignore the error.

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

Hopefully will help someone!
