==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local.

OS X provides libicucore.dylib (but nothing else).

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    LDFLAGS:  -L/usr/local/opt/icu4c/lib
    CPPFLAGS: -I/usr/local/opt/icu4c/include

==> Caveats
Please be aware due to the way Luarocks is designed any binaries installed
via Luarocks-5.2 AND 5.1 will overwrite each other in /usr/local/bin.

This is, for now, unavoidable. If this is troublesome for you, you can build
rocks with the `--tree=` command to a special, non-conflicting location and
then add that to your `$PATH`.
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink bin/luarocks-5.1
Target /usr/local/bin/luarocks-5.1
is a symlink belonging to luarocks. You can unlink it:
  brew unlink luarocks

To force the link and overwrite all conflicting files:
  brew link --overwrite lua51

To list all files that would be deleted:
  brew link --overwrite --dry-run lua51

Possible conflicting files are:
/usr/local/bin/luarocks-5.1 -> /usr/local/Cellar/luarocks/2.1.2/bin/luarocks-5.1
/usr/local/bin/luarocks-admin-5.1 -> /usr/local/Cellar/luarocks/2.1.2/bin/luarocks-admin-5.1
