It seems you have two unrelated errors here.

The first is that Hardy changed how Tkinter is packaged so that 
matplotlib can't find it.  We do not have a workaround for this on the 
0.91.x maintenance branch.  You will need to apply this patch to 
setupext.py:

+@@ -960,6 +960,9 @@ def add_tk_flags(module):
+             if not os.path.exists(tk_inc):
+                 tk_inc = os.path.normpath(os.path.join(tk_lib_dir,
+                                           '../../include'))
++            if not os.path.exists(tk_inc):
++                tk_inc = os.path.normpath(os.path.join(tk_lib_dir,
++                                          '../../../include/tcl' + 
tk_ver))
+            
+             if ((not os.path.exists(os.path.join(tk_inc,'tk.h'))) and
+                 os.path.exists(os.path.join(tcl_inc,'tk.h'))):
+

We have a better fix on the trunk, but it requires more testing.

The second error typically occurs when g++ is not installed.  Try "sudo 
apt-get install g++".

Cheers,
Mike
