Here's what I actually put into my plugins/ directory:

  """Extends sys.path to include the 'site-packages' subdirectory."""

  import sys
  import os
  if getattr(sys, 'frozen', None) is not None:
       sys.path.append(os.path.join(os.path.dirname(sys.executable),
				    'site-packages'))

And the advantage of this over adding to library.zip is not only that
library.zip is left untouched, but also that files in site-packages
will be compiled into *.pyo, while those in library.zip won't.

Thanks again for this tip.
