Our build scripts do not properly npm install from the sassdoc-theme directory on the very first build after cloning, so any unmet dependencies for Sassdoc throw an error on a first build of Phoenix, without much indication on how to work around it. We have logic in place already in both build.sh and build.cmd that is intended to handle this, but it doesn't appear to be robust enough.
Any help on this one would be much appreciated, as it is a blocking bug in the current release.
