I've just started a brand new Crystal app, added Kemal, and when building the "Hello World!" app from the Kemal documentation, I get:
$ crystal build --release src/orderprinterlinks.cr
ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
On OSX 10.12.4
Any ideas why the library is not being found?
