Using vim 7.3 shipped with MacOSX, when trying to complete using omnicomplete (^x^o) it errors with the following messages:

[Pymode] Regenerate autoimport cache.[Pymode]: error: flush

There is no problem when using MacVIM. I'm on 10.9 mavericks.

Relevant configurations in .vimrc:

" Python-mode settings.let g:pymode_options = 0let g:pymode_indent = 1let g:pymode_folding = 0let g:pymode_rope_lookup_project = 0let g:pymode_rope_complete_on_dot = 0

Let me know if you need more information.
