Comment (by easye):

 `ccl` does not currently run on macOS 10.14 Mojave "out of the box", but
 is being actively worked upon.

 For those in immediate need of binaries, please see the snapshot available
 at <https://github.com/Clozure/ccl/releases/tag/v1.12-dev.4>.

 The build procedure has changed a bit with `ccl-1.12`, so the Portfile
 will be modified.

 My preference here would be to wait until there is a single upstream
 source build available that will work across both macOS 10.13 (and earlier
 to the extent possible), and macOS 10.14, rather than conditionalizing the
 portfile based on operating system.

 If someone wants to take a crack at creating such specialized logic, I
 would be happy to pitch in where I can, but otherwise I will wait.
