If /usr/include/sys is a symlink to another location, and the parent
of the other location does not have a net directory, then since it is
a relative cd, it will look up the parent in the link target directory
and not get the directory of the link that brought you there.

In this particular case, the symling is pointing to /usr/src/sys/sys.

And pick something other than 'net', then, like X11.

Oh, yes, I did.  The problem is in the relative pathing used to
go up in the heirarchy resulting in unexpected behaviour.  8-(.


When people say that /usr/include should contain symlinks pointing
to directories, my teeth begin to itch.
