Comment(by ram@…):

 The `qt4` variant seems to work fine for me:

 {{{
 $ port installed py27-matplotlib
 The following ports are currently installed:
   py27-matplotlib @1.0.1_5+qt4 (active)
 $ python
 Python 2.7.2 (default, Aug 22 2011, 13:53:27)
 [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
 Type "help", "copyright", "credits" or "license" for more information.
 >>> import matplotlib
 >>> matplotlib.use("Qt4Agg")
 >>> import pylab
 >>> pylab.plot([1,2,3,4])
 [<matplotlib.lines.Line2D object at 0x1099bcb50>]
 >>> pylab.show()
 }}}

 At which point the appropriate plot is displayed. Can you attach an
 example program that's failing?
