Friday I just put new frameworks and Postgres online, built for Leopard.

I've mentioned a few things on the dev list over the past few weeks  
about GRASS on Leopard.  Summary:

- The current GRASS build does work on Leopard, even with the old  
frameworks.

- X11 starts automatically now when needed.  I know my GRASS startup  
already did this, but it's now done by the system.

- Do NOT set $DISPLAY.  Monitor displays and the GUI will not work.   
DISPLAY is set by the system (and it's not the usual :0.0).

- TclTk 8.4 doesn't build 64bits, so the GUI and NVIZ will not run in  
64bit mode.  Not a big deal for the GUI, but it would be nice to have  
the extra boost in performance in NVIZ.  TclTk 8.5 can build 64bits,  
but I had problems with that in GRASS.

- There is a Leopard linking problem with the X11 libGL (for NVIZ).   
There is a workaround. (only affects compiling GRASS)

- not specificaly GRASS related, but Carbon in Leopard is not 64bit- 
enabled.  Carbon is deprecated.  Carbon is dead.  Anything that  
depends on Carbon must be updated to use Cocoa APIs to work in  
64bits.  This includes Qt (Qgis, OSSIM, ...), some Python GUI type  
stuff, some random libraries (Xerces, used in GDAL).

For GUI stuff, it's not a big problem, as long as the commands (ie  
GRASS modules) run from a GUI do so as a separate process, they will  
run in 64bits if they can.
