[plt-scheme] frtime slowing down

Hi Greg,

Do I need to recompile stuff too? Not sure how to do that...
I get:

compile: variable not provided (directly or indirectly and at the
expected position) from module:
|,/usr/local/lib/plt/collects/frtime/frp-core| in: super-lift

Don't spend too much time on this, I should probably start working on v4
anyway.
