Building ruby/tcltk on Mac OSX

[Mike]

Building the TclTk extension on Max OS X (10.2.3)

1. Additions to 'extconf.rb' (justs bypasses all the config stuff)

5,15d4
< if /darwin/ =~ RUBY_PLATFORM
< stubs = enable_config("tcltk_stubs") || with_config("tcltk_stubs")
< $CPPFLAGS += ' -DUSE_TCL_STUBS -DUSE_TK_STUBS' if stubs
< $CPPFLAGS += ' -DMAC_OSX_TCL -DMAC_OSX_TK'
< $CPPFLAGS += ' -I/Library/Frameworks/Tcl.framework/Headers'
< $CPPFLAGS += ' -I/Library/Frameworks/Tk.framework/Headers'
< $LDFLAGS += ' -framework Tcl -framework Tk'
< create_makefile("tcltklib")
< exit
< end

2. Added '#include <sys/time.h>' to 'tcltklib.c'
(for the definition of 'struct timeval')

3. Added '(const char **)' before 'av' on line 812,
(to avoid an incompatible-type warning)

TRAP_BEG;
ptr->return_value = (*info.proc)(info.clientData, ptr->ip,
argc, (const char **)av);
TRAP_END;


It builds OK.
The demos draw their windows, but the windows never activate.
Clicking on a window gives an message:

SetFrontProcess failed,-606

which is some stupid Apple message.
You have to go to another shell to find the PID to kill it.
Any clues?
