--- Comment #23 from Hime Haieto <himehaieto at gmail dot com> --- Relax, we're still working to pinpoint where the actual problem/solution is. I only confused the src/build stuff for the raw makefile rule - you may not have seen the rest of the Makefile.am and its history within the commit I referenced. Hard-coded paths abound, whether in source or build (though most were indeed removed). I don't think the paths are the issue itself with this picture, so much as it's just a common smell I've come across that shenanigans may be at play, or some subtleties from broken autotools conventions, etc.
