 First, install the required dependencies:
 
-* FreeBSD 11 for amd64 (64-bit).  It is extremely difficult to
-coordinate the LLVM version, operating system support for atomics, and
-Pony to work in harmony on FreeBSD 10 or earlier.  (See additional
-info below that mentions problems with 32-bit executable support.)

+* Pony is currently supported on FreeBSD12 for amd64 (64-bit) using LLVM 7
