3 minor bugs have been fixed (svn and box.net have been updated).
1. OpenOpt required pylab (matplotlib) installed for problems with p.plot turned off as well.
2. p.check.df didn't work with LSP and NLSP.
3. Some code related to GNLP and LLSP were not committed into svn (those who had downloaded OpenOpt from box.net didn't encountered any problems).
