Since you are facing multiple issues, let's try and get the simplest
build working and then add stuff in.  First though, it would be
helpful if you told me what devel rpms you needed to install so I
recommend  these on the web page to other users.  BTW, the two pages
most relevant for you with installation information are
http://matplotlib.sf.net/installing.html and
http://matplotlib.sf.net/backends.html.  Make sure you give these a
good read.

From reading your email, I see that you are installing everything to
your home dir, is that right?

Step 1: start with a clean matplotlib src tree.  I don't want to try
  and work with the one where you have hardcoded information in the
  code because then I don't know what is going on.  Just untar the
  tar.gz file in a new dir and start cleanly

Step 2: Edit setup.py and turn all the BUILD flags off, except for
  BUILD_FT2FONT.  Let's try and get a working base install and then deal
  with getting the extension code compiled.

Step 3: Edit setupext.py and add any non-standard base dirs in which
  you have installed stuff (eg /home/you/usr, /home/you/usr/local') to
  the basedirs dictionary at the top of that file.  Your platform is
  linux2.

Step 4: Install matplotlib with > python setup.py install

Step 5: If the build doesn't finish cleanly (the only reason I can
  think it would fail is if you don't get ft2font built properly.
  This package requires lib freetype so make you have the freetype and
  freetype-devel libs installed.  It also requires libz so make sure
  you have zlib and zlib-devel installed.  If you have installed these
  to a nonstandard place, make sure you add the basedir to setupext
  basedirs.

Step 6: OK, I'm assuming you have a clean install at this point.  If
  you installed with a non-standard prefix, you need to set your
  MATPLOTLIBDATA environment variable.  This data should point to the
  dir that contains, for example, all the Vera*.ttf files.  Eg,
  /your/install/prefix/share/matplotlib.  If you add this to your rc
  file, make sure you resource your rc or open a new shell.

Step 7: At this point, if you have numarray and pygtk installed
(1.99.16 or later), you should be able to import matplotlib.  Open up
python shell and make sure you can do

   >>> import pygtk
   >>> pygtk.require('2.0')
   >>> import gtk
   >>> import numarray
   >>> import matplotlib

  If not, let us know what error you are getting.  You should now be
  able to run python simple_plot.py -dGTK

  
Step 8: Edit setup.py and add the other build flags back in.  You can
  set the ones you want to build to 'auto', which will try and build
  an extension if the python dependencies are found.  If you still
  have problems with arrayobject.h, let me know.  You can add the
  include path to that file in the build_image method in setupext.py
  by doing

      module.include_dirs.append('/your/path/to/numerix/headers')
    
  ie, /home/karthik/usr/include/python/numarray


We do want to improve the build process for people who have stuff in
non-default locations, and it would be very helpful for us if you tell
us explicitly what you had to add and change in the steps above so we
can incorporate as much as possible into the default.

Good luck!
