It was printing `repeat(n, <line-names>)` for number TrackRepeat.
But it should just print n times <line-names> instead.

mach: Fail properly if we can't find the path for OSMesa or GLAPI.
Currently we check `if not (osmesa_path and glapi_path)` after using
`path.join`. It seems we actually want to check whether
`find_dep_path_newest` returns something, because if calls to that
function fail, we'll instead get an error from `path.join` about
`NoneType` not having attribute `endswith` (it expects a string), which
preempts this check.
