+
+I finally had some time to look into this again.
+
+I wiped ikiwiki off my system, and then installed version 2.41. I tried installing
+2.46 and get the same error as above, so I'll be using 2.46 below. (BTW, the debian
+page still lists 2.45 as current; I had to fiddle with the download link to get 2.46).
+
+After running `./Makefile.PL` I get:
+
+ $ perl -Iblib/lib -V
+ [bunch of lines snipped]
+ @INC:
+ blib/lib
+ [bunch of paths snipped]
+
+Running the strace:
+
+ $ strace perl -Iblib/lib -e 'use IkiWiki' 2>&1 |grep IkiWiki.pm
+
+I get a bunch of ENOENTs and then at the end:
+
+ stat64("./IkiWiki.pmc", 0xbfa2fe5c) = -1 ENOENT (No such file or directory)
+ stat64("./IkiWiki.pm", {st_mode=S_IFREG|0644, st_size=31987, ...}) = 0
+ open("./IkiWiki.pm", O_RDONLY|O_LARGEFILE) = 3
+
+After running `make` (and having it fail as described above):
+
+ $ strace perl -Iblib/lib -e 'use IkiWiki' 2>&1 |grep IkiWiki.pm
+ stat64("blib/lib/IkiWiki.pmc", 0xbfd7999c) = -1 ENOENT (No such file or directory)
+ stat64("blib/lib/IkiWiki.pm", {st_mode=S_IFREG|0444, st_size=31901, ...}) = 0
+ open("blib/lib/IkiWiki.pm", O_RDONLY|O_LARGEFILE) = 3
+
+I don't know what is going on, but I'll run any more tests you need me to.

+
+I have 2.46 installed and I can reproduce the bug reported against 2.49. The command that fails is:
+
+ $ /usr/bin/perl -Iblib/lib ikiwiki.out -libdir . -setup docwiki.setup -refresh
+ docwiki.setup: Failed to load plugin IkiWiki::Plugin::inline: Too many arguments for IkiWiki::htmlize at IkiWiki/Plugin/inline.pm line 359, near "))"
+ Compilation failed in require at (eval 14) line 2.
+ BEGIN failed--compilation aborted at (eval 14) line 2.
+ BEGIN failed--compilation aborted at (eval 10) line 21.
+
+strace -f produces a 112K file. I don't know enough to be comfortable analyzing it.
+However, lines like:
+
+ stat64("/usr/local/share/perl5/site_perl/5.10.0/IkiWiki.pm", {st_mode=S_IFREG|0444, st_size=31982, ...}) = 0
+
+make me think the make process is not completely independent of a previous
+installation. Joey, should I email you the strace log file?

+
+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.
+

+
+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.
