Everything is described in this post: http://www.nabble.com/Error-compiling-tk-8.5.7-on-Mac-OS-X-10.5-td23790967.html

But here's a script too: curl -O 'http://osdn.dl.sourceforge.net/sourceforge/tcl/t{cl,k}8.5.7-src.tar.gz'for f in t*8.5.7*.gz; do tar zxf $f; done cd tcl8.5.7/unix/./configure --enable-framework --enable-64-bitcd tk8.5.7/unix/./configure --enable-framework --enable-64-bitmake -j 4 -C tcl8.5.7/unix make -j 4 -C tk8.5.7/unixsudo make install -C tcl8.5.7/unix sudo make install -C tk8.5.7/unix

Concerns:

• might be necessary to do this in the macosx directory for some reason, though Aqua doesn't support 64 bits
• have to recompile python to get _tkinter to work (see a later post)
