So I switched to incoming, completely cleaned all of the byte code and
started a new terminal session. All the compilation went fine until the
very last link to JS:
Traceback (most recent call last):
File "/Users/tlinton/Library/Emscripten/emscripten/incoming/emcc", line
1478, in <module>
extra_files_to_link = system_libs.calculate(temp_files, in_temp, stdout,
stderr)

line 360, in calculate

shared.Settings.EXPORTED_FUNCTIONS.append('_' + dep)
AttributeError: 'str' object has no attribute 'append'
ninja: build stopped: subcommand failed.
