+Joey, thanks for your time and effort looking into this.
+
+I checked with `which`: `perl` is indeed `/usr/bin/perl`. The commands fail similarly when
+calling `perl` and `/usr/bin/perl`.
+
+However, you might be into something with your `libdir` idea. If I remove it from the
+command line, the command succeeds. In other words, if I run
+
+    perl -Iblib/lib   ikiwiki.out -setup docwiki.setup -refresh
+
+then it works perfectly.
+
+> Well, that's just weird, because `libdir` is handled by code in IkiWiki.pm.
+> So I don't see how setting it could affect its searching for IkiWiki.pm at all,
+> actually. It could only affect its searching for files loaded later. Anyway,
+> can I get a strace of it succeeding this way?
+> 
+> Also, can you show me the first 15 lines of your `ikiwiki.out`? It's occurred to me
+> you might have an unusual `use lib` line in it.
+
+By the way, I'm running Arch linux. The perl build script is a bit long, but I
+see they install a patch to modify @INC: <http://repos.archlinux.org/viewvc.cgi/perl/repos/core-i686/perl-5.10.0-archlinux-inc-order.patch?revision=1&view=markup>
+
+Would you suggest I try rebuilding perl without this patch? Debian has a huge perl patch (102K!);
+it's not straightforward for me to see if they do something similar to Arch.
+
+> I think Debian has a similar patch.

+[[done]] -- apparently this was a problem due to a distribution's
+customisation to perl, or something. Seems to late now to track down what,
+unfortunatly. And ikiwiki's Makefile no longer uses the "-libdir" switch
+that seemed to trigger the bug. --[[Joey]]
