[cairo] Pycairo: can't find python devel header files?

[Dimiter 'malkia' Stanev]

Hi Fabrice,

I think this might be a Python installation problem, rather than cairo.

Maybe you need to make your python with --enable shared, as in:

make clean; configure --enable-shared --prefix=/usr --sysconfdir=/etc 
--localstatdir=/var; make; make install

It could be that libm.so/.dylib/.dll would be loaded later somehow.

Thanks,
