macosx10.10-qt was derived from an out of date version of
macosx10.10. This tries to make combined X11+Qt behave sanely but
I have no way of testing it.
It appears to require homebrew, at least that's what the construct
$(shell brew ...) to set up QTDIR suggests. That seems iffy and
should at least be documented.
It includes tty along with Qt but lacks support for including the
curses interface so definitely needs more updating.
Change all the POSTINSTALL 'mkfontdir' to 'mkfontdir -x .lev' although
the mkfontdir version on my system didn't think $(HACKDIR)/*.lev were
font files when I built without dlb.
Also change the PREINSTALL 'cp -n win/X11/nethack.rc ~/.nethackrc' to
keep going if it fails. The linux hints use 'cp -n' for sysconf but
since it is doing so for the playground directory and 'make install'
starts out by clearing away everything in that directory, it shouldn't
fail. But some extra bullet proofing there may be warranted. Only
the initial cp is protected against clobbering an existing file; the
ownership+permission fixups that are applied to the copy of original
file still get applied to an existing one.
