[O] make install-info error messages

[Greg Minshall]

hi.  i'm trying to install 7.8.11 on my Mac OS X system (running Emacs
24.1.1.  i've changed Makefile (see below) in terms of emacs (to point
to 24.1.1) and prefix (to install in ~/usr).  install-info give the
following set of error messages (and, the web page says "please submit a
bug"):
----
bash greg-minshalls-mbp: {1046} make install-info
(cd doc && makeinfo --no-split org.texi -o org)
if [ ! -d /Users/minshall/usr/share/info ]; then \
                mkdir -p /Users/minshall/usr/share/info; else true; fi ;
cp -pr doc/org /Users/minshall/usr/share/info
install-info --infodir=/Users/minshall/usr/share/info doc/org
* Org Mode: (org). Outline-based notes management and organizer
install-info(doc/org): replacing existing dir entry for `org'
cp: /var/backups/infodir.bak: Permission denied
install-info(doc/org): couldn't backup /Users/minshall/usr/share/info/dir in 
/var/backups/infodir.bak: Inappropriate ioctl for device
----
(obviously (?), i was *not* doing this as root...)

cheers, Greg Minshall
