This is done by default on Lion because there is no stable build of WxPython available to compile against. The command line tools remain fully functional. EOS else <<-EOS.undent GRASS is currently in a transition period with respect to GUI support. The old Tcl/Tk GUI cannot be built using the version of Tcl/Tk provided by OS X. This has the unfortunate consquence of disabling the NVIZ visualization system. A keg-only Tcl/Tk brew or some deep hackery of the GRASS source may be possible ways to get around this around this. Tcl/Tk will eventually be depreciated in GRASS 7 and this version has been built to support the newer wxPython based GUI. However, there is a problem as wxWidgets does not compile as a 64 bit library on OS X which affects Snow Leopard users. In order to remedy this, the GRASS startup script: #{prefix}/grass-6.4.0/etc/Init.sh has been modified to use the OS X system Python and to start it in 32 bit mode.
