Perhaps we want a GUI Planet2 installation tool? And options for
auto-install from DrRacket to be silent, confirm/cancel, or auto-fail?
That would give us the range from full manual control to automatic

I've run into the same issue. The way I sometimes to it is to eval
code which requires the original module for syntax, extracts the value
during macro expansion, and produces an expression that quotes it (or
an expression that reconstructs it, if not an s-expression).
