How can I install aggdraw after this error?

I am trying to install the aggdraw python library to create high quality graphics but I keep getting this error:

agg22/include/agg_array.h: In member function `agg::int8u*

What is the workaround for this? How can I install it?

You should follow the instructions in http://www.pocketuniverse.ca/archive/2008/december/11/pil-and-aggdraw/ to patch AGG rather than just have the compiler allow the 64-bit incompatible code to compile.

Here's one way you could do it in the shell:

cd /tmp
svn co http://svn.effbot.org/public/tags/aggdraw-1.2a3-20060212
cd aggdraw-1.2a3-20060212
patch -p0 <<EOF

python setup.py build_ext -i
python selftest.py
sudo python setup.py install

(Yes I am answering my own question)

After searching a lot through the web I found that doing

export CFLAGS="-fpermissive"

before building the extension with python setup.py build_ext -i seemed to do the trick.
