[ryandesign (Ryan Carsten Schmidt)]

gnubg does not build on the buildbot workers:

checking consistency of all components of python development environment... no
configure: error: in '/opt/local/var/macports/build/_opt_bblocal_var_buildworker_ports_build_ports_games_gnubg/gnubg/work/gnubg-1.05.002':
configure: error: 
  Could not link test program to Python. Maybe the main Python library has been
  installed in some non-standard library path. If so, pass it to configure,
  via the LDFLAGS environment variable.
  Example: ./configure LDFLAGS="-L/usr/non-standard-path/python/lib"
  ============================================================================
   ERROR!
   You probably have to install the development version of the Python package
   for your distribution.  The exact name of this package varies among them.

See 'config.log' for more details

Maybe updating the port will help.
