It looks like the build is failing in the 'ogre' package, trying to
build (well, install) OGRE itself.  I thought that we had a hook in
there to not try to build OGRE on OS X, on the assumption that the
user would have installed it already.  In any case, you might try
touching a file ROS_NOBUILD in the 'ogre' package; that will cause
rosmake to skip over it, and perhaps attempt to build 'ogre_tools'.
