missing gmp

[rdp]

No idea if this is the right place to report this, but at least with 0.18.2

GMP is optional, if you don't use big numbers you don't need it. So we could maybe install it with homebrew, but I don't know. Eventually I think I'd like to implement big numbers without an extra library, just pure crystal.

yes I was using BigRational at the time. However, the link line seems to
anticipate it, I'd add it to homebrew for now, since it's there and part of
the std. lib.
Cheers!
