在CentOS上安装matplotlib时遇到tcl/tk版本不匹配的问题，导致无法正常显示图形。通过注释掉Tkinter.py中检查版本的代码，成功解决了这个问题并能正常展示图形。

按照官网（http://matplotlib.org/users/installing.html）的节奏，安装完其他基本扩展后，在选择tcl/tk作为backend后，遇到tcl/tk头文件版本和tcl/tk库版本不一致的问题，如下：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.6/site-packages/matplotlib/pyplot.py", line 2810, in plot
    ax = gca()
  File "/usr/local/lib/python2.6/site-packages/matplotlib/pyplot.py", line 707, in gca
    ax =  gcf().gca(**kwargs)
  File "/usr/local/lib/python2.6/site-packages/matplotlib/pyplot.py", line 370, in gcf
    return figure()
  File "/usr/local/lib/python2.6/site-packages/matplotlib/pyplot.py", line 343, in figure
    **kwargs)
  File "/usr/local/lib/python2.6/site-packages/matplotlib/backends/backend_tkagg.py", line 79, in new_figure_manager
    return new_figure_manager_given_figure(num, figure)
  File "/usr/local/lib/python2.6/site-packages/matplotlib/backends/backend_tkagg.py", line 87, in new_figure_manager_given_figure
    window = Tk.Tk()
  File "/usr/local/lib/python2.6/lib-tk/Tkinter.py", line 1645, in __init__
    self._loadtk()
  File "/usr/local/lib/python2.6/lib-tk/Tkinter.py", line 1665, in _loadtk
    #    % (_tkinter.TCL_VERSION, tcl_version)
RuntimeError: tcl.h version (8.6) doesn't match libtcl.a version (8.4)

捣鼓了两天，各种搜索，就是解决不了版本不匹配的问题，最后在某处看到，如下做法就成功解决了，也能show()出图形来：
只要把Tkinter.py里面检测头文件和库文件版本的几行代码注销掉就行了.
        #if tcl_version != _tkinter.TCL_VERSION:
        #    raise RuntimeError, \
        #    "tcl.h version (%s) doesn't match libtcl.a version (%s)" \
        #    % (_tkinter.TCL_VERSION, tcl_version)
