+/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]]
+

+Did anyone tried to install ikiwiki under a vhost setup ?
+ikiwiki is installed under a debian lenny system. but without write acces to /etc/ikiwiki (obvious) i am coming not far.
+Or do i miss something which is probably hidden deeper in the documentation ?
+
+Well it should be similar to shared hosting [or a remote server in general](http://ikiwiki.info/forum/how_to_setup_ikiwiki_on_a_remote_host/)
+
+----
+Perhaps it's worth noting that when installing ikiwiki with apt on Debian stable, you need to use the backports version in order to follow the setup instructions.
