I am trying to setup pycairo in virtualenv but setup fails when searching for Python.h header file
(draw)[root@collabdraw pycairo]# python ./waf configure --prefix=/usr
./options()
Setting top to : /root/pycairo
Setting out to : /root/pycairo/build_directory
./configure()

Checking for header Python.h : :-(
Asking python-config for the flags (pyembed) : yes

Getting pyext flags from python-config : Could not build python extensions
The configuration failed
(complete log in /root/pycairo/build_directory/config.log)
Any ideas why python ./waf configure --prefix=/usr cannot find Python.h? This file is located in virtaulenv directory
(draw)[root@collabdraw pycairo]# ls ~/virtualenvt/draw/include/python3.2m/Python.
Python.h ##### This is the file
