+OK, this is what I'm getting:
+
+    $ perl -Iblib/lib -V
+    @INC:
+    blib/lib
+    /usr/lib/perl5/site_perl/5.10.0
+    /usr/share/perl5/site_perl/5.10.0
+    /usr/lib/perl5/vendor_perl

+    /usr/share/perl5/vendor_perl
+    /usr/lib/perl5/core_perl
+    /usr/share/perl5/core_perl
+    /usr/lib/perl5/current
+    /usr/lib/perl5/site_perl/current
+
+I ran the following in my current 2.45 source dir, where the `make` already succeded. If you need it, I can post the output
+in the case where `make` fails.
+
+    $ strace perl -Iblib/lib -e 'use IkiWiki' 2>&1 |grep IkiWiki.pm
+    stat64("blib/lib/IkiWiki.pmc", 0xbfa6167c) = -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 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?
