Docs build error

[gbpoole]

On OSX using mactex as my latex distribution, installed with Home-brew, I get the following docs build error:

rm -f doc/manual-single.html
/bin/sh '/Users/gpoole/temp3/.gbpEnv/stow/automake/missing' makeinfo --html -I . -I doc -I ./doc
-c USE_TITLEPAGE_FOR_TITLE=1 --no-split -o doc/manual-single.html
test -f 'doc/stow.texi' || echo './'doc/stow.texi
makeinfo: invalid option -- c
Try `makeinfo --help' for more information.

I'm afraid I don't have a Mac to try this out on, but maybe this is an issue with an old version of makeinfo?
