db setup requires libicui18n.52.1.dylib, but brew installs 53.1

Workaround is to switch to the older version:

➜  gitlab git:(master) brew switch icu4c 52.1
Cleaning /usr/local/Cellar/icu4c/52.1
Cleaning /usr/local/Cellar/icu4c/53.1
Opt link created for /usr/local/Cellar/icu4c/52.1

From a brand new clone:

Forgot to mention: on latest OS X

What happens if you switch back to the latest ICU, run gem uninstall charlock_holmes, and then run bundle install again for the Rails app?

Charlock Holmes works fine for me with icu4c 53.1 on OS X 10.9.4.

Switching to 53.1, uninstalling charlock_holmes and then running bundle install works for me. Perhaps I had an old charlock_holmes gem present in my ruby?

Status changed to closed by commit edf631

@juytven that would be my guess. I added some tips to the README based on this.
