+I setup ikiwiki on a fedora 10 machine and I am using apache as my http server. Faced a few difficulties while setting it up as the default setup program left some suid files and group writeable directories on the system. It took some time to get it working and documented what I did at http://flyingtux.blogspot.com/2009/03/installing-ikiwiki.html. Thought it might be useful to someone here. (The version installed is 2.72)
+
+> ikiwiki makes wrappers suid by default, because this ensures that when
+> the ikiwiki.cgi is run by your web server, it runs as the user who owns
+> your wiki, and can thus write to it. ikiwiki is designed to run securely
+> suid. If your webserver uses some
+> mechanism to run the ikiwiki.cgi as the user who owns it, without the
+> suid bit being set, you *could* modify `cgi_wrappermode` in your setup
+> file to drop the suid bit.
+>
+> ikiwiki respects the umask, so if your umask is one that causes things to
+> be group writable, they will by. If you want to override that, there is
+> also a `umask ` setting in your setup file. --[[Joey]]

+
+/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:
+
+<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 ~]$
+</pre>
+
+Because of this, /etc/ikiwiki/auto.setup fails:
+
+<pre>
+$ ikiwiki -setup /etc/ikiwiki/auto.setup
+What will the wiki be named? wiki
+What revision control system to use? git
+What wiki user (or openid) will be admin? mort
+
+

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

+
+Thank you! I'm not a Perl programmer, so what's your opinion: is this behavior a violation of the specification of abs_path and I should report it to [ALTLinux](http://bugs.altlinux.org) (the distro)? --Ivan Z.

+
+I am experiencing the same problem "/etc/ikiwiki/custom: failed to set up the repository with ikiwiki-makerepo
+" on Debian squeeze with perl5.10.0. Upgrading to ikiwiki 3.10 fixes it. -- [Albert](http://www.docunext.com/)
+
+----
+
+Just a note, perl 5.10 isn't packaged as part of RHEL or thus CentOS nor EPEL,
+so it's not especially trivial to satisfy that requirement for ikiwiki on
+those platforms, without backporting it from Fedora or building from source.
+However, I have an ikiwiki 3.20100403 running on RHEL-4 supplied 5.8.8 without
+(seemingly too much) complaint. How strong is the 5.10 requirement? what
+precicely breaks without it? -- [[Jon]]
