The best I might be able to implement before 2.7 goes into beta is a hack where Tkinter gets linked to Tk 8.4 when the deployment target is 10.5 or earlier. That would allow building the binary distribution on 10.6 and would result in a working copy of IDLE. Supporting Tk 8.5 would be nice, but is not something I can spend time on at the moment (due to lack of time to do the work). What's important for me: * The distribution on python.org must work on OSX 10.4 or later * IDLE must work on all supported platforms * Users should not have to install Tcl/Tk, Python should use the system install and optionally use a user install in /Library when that is available Ronald > > -- > Ned Deily, > n...@acm.org > > _______________________________________________ > Pythonmac-SIG maillist - Pythonmac-SIG@python.org > http://mail.python.org/mailman/listinfo/pythonmac-sig > unsubscribe: http://mail.python.org/mailman/options/Pythonmac-SIG
