Apple has migrated its X11 suite (xquartz) to /opt/X11 for the past few
OS X major releases, but they have retained some symlinks from /usr/X11
and/or /usr/X11R6 so that we can still access headers and libs via
-I/usr/X11/include and similar. A few years ago, they temporarily
dropped a symlink, and many things became uncompileable unless one knew
to pass --x-includes= and --x-libraries paths. Rumor is they might be
doing it again in the next release. If I patch libs.m4 to place
/opt/X11/include in the ac_x_header_dirs default search paths list, X11
is detected correctly.
Fink has deployed a patch that works as I described for the past
several months, worked fine on both old and new OS X machines. Max Horn
wrote a clean patch against autoconf git that implements it. Please let
us know if you need additional info or explanations...obviously OS X is
not a platform everyone has access to test.
