   I followed the build script. It seemed to work (but I su'd to root to
write to /tmp), until the next to last command: there's no requiredbuilder
on my system.

   There is a lot of Python setup.py builds and installs because wxPython is
dependent on wxWidgets and wxGTK.

   I've attached the script. When I ran it on the source tarball, it did
produce a package, so I don't know why the requiredbuilder step failed when
I ran it manually.

# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in.  You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':'.

wxpython: wxPython (Python GUI development)

wxpython: wxPython is a GUI toolkit for the Python programming language. It
wxpython: allows Python programmers to create programs with a robust, highly
wxpython: functional graphical user interface, simply and easily. It is
wxpython: implemented as a Python extension module (native code) that wraps
wxpython: the popular wxWidgets cross platform GUI library, which is written
