[Matplotlib-users] Debian, TkAgg, can't find "tk.h"

[Eric J. <jo...@co...>]

When compiling matplotlib on debian with :
python setup.py install --home=/home/jonas/python

I get an error message about not being able to find tk.h (appended
below). This is with (I believe) all necessary tk libraries installed.
When I set CPATH=/usr/include/tcl8.4 and then try, it compiles just
fine. Is there any way we could make the tk-finding code a bit smarter
so it would work out of the box on debian? 

Thanks for such an amazing plotting package -- at last, I might be able
to ditch matlab!
