ADL: ADT problems on Mac OS 10.5 and Leopard

Hi Sargis,

Many thanks. But some additional clarification is still needed,  
particularly with regard to the order of doing things:

1. I assume one needs to install, as a first step, Python 2.5. The  
Leopard version I have (10.5.2) ships with Python 2.4.

2. Is the next step the replacement of the Leopard X11 by the Tiger  
version? If yes, does one follow the procedure given in
or it would simply suffice to replace the Leopard /usr/X11R6  with  
that from another machine with Mac OS X 10.4 as you suggest?

3. Finally, does one install MGL Tools from the binary installer or  
from the source?

Your clarifications/suggestions etc would be of great help.

All the best
