Error installing iconv

Today I was trying to install the iconv gem, and was getting this error

$gem install iconv
Building native extensions.  This could take a while...
ERROR:  Error installing iconv:
	ERROR: Failed to build gem native extension.

        <rvm_dir>/rubies/ruby-2.0.0-preview2/bin/ruby extconf.rb

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:

Gem files will remain installed in <rvm_dir>/gems/ruby-2.0.0-preview2/gems/iconv-1.0.2 for inspection.
Results logged to <rvm_dir>/gems/ruby-2.0.0-preview2/gems/iconv-1.0.2/ext/iconv/gem_make.out

After a bit of searching, I found a number of answers suggesting that I would need to reinstall ruby via RVM, but in the following StackOverflow question

In it was the solution:
gem install iconv -- --with-iconv-dir=/usr/local/Cellar/libiconv/1.13.1

After that, all was well.
