Thanks tka, that seemd to be the problem, for whatever reason.
This works for me now:

#modname "Cheap Wish"
#description "Makes WISH really cheap in order to experiment"
#Version 0.1

#selectspell "wish"
#fatiguecost 100
#researchlevel 1
#pathlevel 0 1
#end

Wish now shows up as an astral-1 spell costing 1 pearl, requiring Alt-1.
thanks much
