Re: [Matplotlib-users] Building Matplotlib 0.87 on os X

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

I found wx-config in
/usr/local/lib/wxPython-ansi-2.6.2.1/bin

./wx-config --version
2.6.2

there is another wx-config in /usr/bin that returns 2.5.3 for the  
version

in setupext.py  is the following function

def find_wx_config():
     """If the WX_CONFIG environment variable has been set, returns  
it value.
     Otherwise, search for `wx-config' in the PATH directories and  
return the
     first match found.  Failing that, return None.
     """

     wxconfig = os.getenv('WX_CONFIG')
     if wxconfig is not None:
         return wxconfig

     path = os.getenv('PATH') or ''
     for dir in path.split(':'):
         wxconfig = os.path.join(dir, 'wx-config')
         if os.path.exists(wxconfig):
             return wxconfig

     return None

I checked and I didn't have WX_CONFIG environment variable set to  
anything.

so I set the environment variable

export WX_CONFIG="usr/local/lib/wxPython-ansi-2.6.2.1/bin/wx-config"
AlBook:smithsm$ echo $WX_CONFIG
usr/local/lib/wxPython-ansi-2.6.2.1/bin/wx-config

I removed the build directory rm -r build then I
python setup.py clean
python setup.py build
sudo python setup.py clean

but the problem does not go away!
  from the debug output below it states that
the WXAgg backend is version 2.6.2.1
So I don't know what to do?
