Hi all,
How can I resolve the following backend problem ?
What are the default library and include directories for tcl and tk ?
Where should I define DISPLAY in that context ?
python setup.py build --help
OPTIONAL BACKEND DEPENDENCIES
libpng: 1.2.7
Tkinter: Tkinter: 50704, Tk: 8.4, Tcl: 8.4
* Using default library and include directories for
* Tcl and Tk because a Tk window failed to open.
* You may need to define DISPLAY for Tk to work so
* that setup can determine where your libraries are
* located.
Any pointer would be appreciated.

What platform are you on?
There is apparently no good way to find the path to the Tcl/Tk header files. The setup script currently tries to import Tkinter, and create a window, in order to make an API call that returns the path. (Crazy, I know). Therefore, if it can't create a window (for example you're on a remote terminal without X forwarding), this will fail. In that case, matplotlib uses a hardcoded path to Tcl/Tk which is platform-specific. Does it fail to compile the TkAgg backend later on? If so, can you send the compiler output message? That will at least show us where it is looking for the Tcl/Tk header files.
Note that different versions of Tcl/Tk and different Linux distributions put these files in different places, so it's a constant battle to keep up with the hardcoded paths. If you're running the latest Whiz-bang Linux Alpha, or something, that might explain it.
