Oh yeah, sorry, I forgot about that problem. ;-/ What we do in  
wxWidgets' configure.in script is to alter bk-deps by changing the  
depsmode from gcc to none. Here's the relevant part:

dnl HACK ALERT!!
dnl For now, we need to alter bk-deps not to generate deps
dnl when we've configured a Universal binary build.
dnl The next version of Bakefile will have the correct fix for this
dnl at which time, this hack can be removed.

if test "$wxUSE_MAC" = 1 ; then
     if test "x$wxUSE_UNIVERSAL_BINARY" != "xno" ; then
         sed "s/DEPSMODE=gcc/DEPSMODE=none/" < bk-deps > temp
         mv temp bk-deps
         chmod +x bk-deps
     fi
fi

Kevin
