Ah, now I see. Yeah, this is one of the nice things that libtool does
for you that we don't get with Mesa's custom build. We're not linking
the app directly to libXdamage, but instead it's being picked up by
the linker as being needed by libGL. Since we don't tell the linker
anything special about how to find libXdamage, it searches in the
system default libraries and finds /usr/lib/libXdamage.

If you're using GCC and GNU ld, you can build with
LDFLAGS="-Wl,-rpath,$yourdir/lib" if you're not installing to the
system default locations. You can pass that as an argument to Mesa's
configure. This is something that libtool does for you, but it's a ton
of logic to duplicate. Maybe someday.
