+Darwin is also known as Mac OS X.  Beware that this system @emph{can} be
+case-preserving, but case insensitive.  This can cause nasty problems,
+since for instance the installation attempt for a package having an
address@hidden file can result in @samp{make install} report that
+nothing was to be done!
+
+That's all dependent on whether the file system is a UFS (case
+sensitive) or HFS+ (case preserving).  By default Apple wants you to
+install the OS on HFS+.  Unfortunately, there are some pieces of
+software which really need to be built on UFS.  We may want to rebuild
+darwin to have both UFS and HFS+ available (and put the /local/build
+tree on the UFS).
