When I tried to install Octave (brew install octave --with-gui --HEAD) on OS X 10.11.2 I got this error:

You might have modified some files without having the proper
tools for further handling them. Check the 'README' file, it
often tells you about the needed prerequisites for installing
this package. You may also peek at any GNU archive site, in
case some other package contains this missing 'rsvg-convert' program.
