1. Edit Makefile, it should only need to change were SoM is located
2. Enable Equatable and Comparable

diff --git a/Versions/StaticVersion.swift b/Versions/StaticVersion.swift
index 82c19e3..c80ab37 100644
--- a/Versions/StaticVersion.swift
+++ b/Versions/StaticVersion.swift

3. Run make

[stephen-hawley]

The Element error is due to it being an associated type.
The Character error is not in the SwiftRuntimeLibrary. Yet.
