Unsufficient privileges on directory /usr/share/dokuwiki/lib/plugins/

There are also unsufficient privileges on the /usr/bin/abcm2ps file that make it impossible to configure dokuwiki using its web interface.

Sorry, I indicated a wrong file path above, bad copy/paste.
You should read /etc/dokuwiki/dokuwiki.php instead of /usr/bin/abcm2ps

I am working on offering, via debconf, the choice to make the plugins writeable by the web server. The updated package should be available soon in Debian unstable, and then in Ubuntu.

This bug was fixed in the package dokuwiki - 0.0.20091225c-8
