Another solution is to fix the script.

According to 
http://standards.freedesktop.org/basedir-spec/basedir-spec-0.6.html, the 
default values are well defined.

So, instead of just doing:
export XDG_DATA_DIRS="$PREFIX/share:$XDG_DATA_DIRS"

You could do add the default:
XDG_DATA_DIRS="$PREFIX/share:"${XDG_DATA_DIRS-/usr/local/share/:/usr/share/}

Testing it:
$ echo $XDG_DATA_DIRS

$ 
XDG_DATA_DIRS="$KDEDIR/share:"${XDG_DATA_DIRS-/usr/local/share/:/usr/share/}
$ echo $XDG_DATA_DIRS
/usr/local/kde3-r500000//share:/usr/local/share/:/usr/share/
