tcl include bug in setupext: should it be finally corrected once and for all?

Hi,

just downloaded the last version of matplotlib (matplotlib-0.87.2.tar.gz) and the bug in setupext.py is still there... I AGAIN have to :
# add one line in setupext.py:

        o.tcl_inc="/usr/include/"

# before
        if not os.path.exists(o.tcl_inc):
            print 'cannot find tcl/tk headers. giving up.'
            sys.exit()
    return o

so that it works.

Is there a way that this bug could be corrected once and for all (or is it that I am doing something wrong?)

thanks
Eric
