Hi,
Gentoo has encountered the same problem:
<http://bugs.gentoo.org/show_bug.cgi?id=306445#c7>
Another related issue is that files beginning with the string "dir"
cannot be opened, e.g. "dired-x" (which is included with emacs):
<http://bugs.gentoo.org/show_bug.cgi?id=340697>
Attached are two patches that should fix these issues. (They are
against pinfo-0.6.9, but can be cleanly applied for 0.6.10 too.)
