The presence of the tk library determines whether python's compile
task will build tkinter. Then the presence of python-tkinter in
IMAGE_INSTALL will then determine whether it is installed.
In the absence of tk provided by meta-oe, the python recipe will
install an empty python-tkinter package.
I cannot think of a cleaner way to do this right now. Ideally the
package python-tkinter could trigger a python DEPENDS on tk...
Martin, you originally suggested the PACKAGECONFIG. Do you have any
further thoughts on this?
