[Vimoutliner] My VO does not work anymore

[on_]

Hi there,

I'm new here. I use GVim and VimOutline for my work. I only use basic
features of them. I'm runing it under Ubuntu 7.10. And 'till now
everything was fine.

Last time I use VO, I worked on a big outline a month ago... Today, I
tried to open this .otl file, GVim opened it but without VO. I tried to
open other .otl files, from within GVim, by double-clicking them
directly in Nautilus and at the commandline. Nothing worked. I
unsinstalled and reinstalled VO. ... ... Worst, I figured out that my
GVim does not include VO anymore, as ":he vimoutliner" returned an E149
errorcode.

Could you help me bringing VO back to live on my system?

Thanks in advance,
