Arch Linux

Description:
The PKGBUILD for Dokuwiki installs plugins in /var/lib/dokuwiki/plugins (which is the app's data directory) instead of the code directory, namely /etc/webapps/dokuwiki/plugins. This cause at least a plugin (godiag) to fail, since it navigates through the tree using relative paths and it ends up in the wrong place.

See discussion on Dokuwiki's forums: https://forum.dokuwiki.org/thread/16658

Additional info:
* package version(s): 20180422_b

Steps to reproduce:

1. Install dokuwiki
2. Install the godiag plugin from within dokuwiki's own extension manager
3. Create a new go diagram inside a new page, as per godiag instructions (see xa here: https://www.dokuwiki.org/plugin:godiag)
4. Save and see the diagram NOT getting rendered
5. See the error in the web server log.

The "problem" is caused by these lines in the PKGBUILD:
# move plugins in var
mv usr/share/webapps/dokuwiki/lib/plugins var/lib/dokuwiki
ln -s {../../../../../../var/lib/dokuwiki,usr/share/webapps/dokuwiki/lib}/plugins

According to the Dokuwiki people, the plugins should remain in /etc/webapps/dokuwiki and not be moved. See the forum discussion referred above for why only some plugin suffer from this mis-location and how manually hardcoding the correct path into one of the plugin's php modules works around the issue.
