==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local.
Mac OS X already provides this software and installing another version in
parallel can cause all kinds of trouble.
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/libiconv/lib
CPPFLAGS: -I/usr/local/opt/libiconv/include

% brew link libiconv
Warning: libiconv is keg-only and must be linked with --force
Note that doing so can interfere with building software.
