 And it is also broken on the freshly release Fedora Core 10:
 {{{
 BUILDING MATPLOTLIB
              matplotlib: 0.98.3
                  python: 2.5.2 (r252:60911, Nov 25 2008, 20:08:09)  [GCC
                          4.3.2 20081105 (Red Hat 4.3.2-7)]

 REQUIRED DEPENDENCIES
                   numpy: 1.2.0
               freetype2: 9.18.3
 OPTIONAL BACKEND DEPENDENCIES
                  libpng: 1.2.33
 Traceback (most recent call last):

      if check_for_tk() or (options['build_tkagg'] is True):

      explanation = add_tk_flags(module)
    File

      module.libraries.extend(['tk' + tk_ver, 'tcl' + tk_ver])
 UnboundLocalError: local variable 'tk_ver' referenced before assignment
 Error building matplotlib package.
 }}}
 So let's make this a blocker.

 Cheers,

 Michael
