Installing 64 bit tcl/tk on Mac OS X

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-bit
cd tk8.5.7/unix/
./configure --enable-framework --enable-64-bit
make -j 4 -C tcl8.5.7/unix
make -j 4 -C tk8.5.7/unix
sudo 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)
