 /etc/ikiwiki/auto.setup tries to get abs_path of a non-existent "repository" path (in ikiwiki-makerepo), and that doesn't work in my perl:
 
-<nowiki>
+<pre>
 [mort@localhost ~]$ perl -e 'use Cwd q{abs_path}; print abs_path("/var")'
 /var[mort@localhost ~]$ perl -e 'use Cwd q{abs_path}; print abs_path("/abcde")'
 [mort@localhost ~]$ 
-</nowiki>

 Because of this, /etc/ikiwiki/auto.setup fails:

 What revision control system to use? git

 Can't ikiwiki's "make test" perhaps test for this, so that one knows something will go wrong?
