[PYTHON] Freetype2 support not available on PIL when trying to blockdiag on CentOS6.5

background

I have a tool called blockdiag that creates a nice block diagram with sphinx. I was moss when I tried to use it, so make a note

If you get the The _imagingft C module is not installed error

0. Uninstall PIL with pip or easy_install

1. Install what you need

yum install zlib zlib-devel
yum install libjpeg libjpeg-devel
yum install freetype freetype-devel
yum install fontconfig-devel

2. Check the location of ft2build.h and freetype

find / -name "ft2build.h"
/usr/include/ft2build.h

find / -name "freetype"
/usr/include/freetype2/freetype

3. Place ft2build.h in the same location as freetype

cp /usr/include/ft2build.h /usr/include/freetype2

4. Compile PIL yourself

mkdir -p ~/src ~/lib/python2.7
cd ~/src
wget http://effbot.org/media/downloads/PIL-1.1.7.tar.gz
tar zxf PIL-1.1.7.tar.gz
cd PIL-1.1.7

# Library pointers.
#
# Use None to look for the libraries in well-known library locations.
# Use a string to specify a single directory, for both the library and
# the include files.  Use a tuple to specify separate directories:
# (libpath, includepath).  Examples:
#
# JPEG_ROOT = "/home/libraries/jpeg-6b"
# TIFF_ROOT = "/opt/tiff/lib", "/opt/tiff/include"
#
# If you have "lib" and "include" directories under a common parent,
# you can use the "libinclude" helper:
#
# TIFF_ROOT = libinclude("/opt/tiff")

TCL_ROOT = None
JPEG_ROOT = '/usr/lib64','/usr/include'
ZLIB_ROOT = '/lib64','/usr/include'
TIFF_ROOT = None
FREETYPE_ROOT = '/usr/lib64','/usr/include/freetype2/freetype'
LCMS_ROOT = None

5. Confirmed operation with python2.7 setup.py build_ext -i
