sqlite3 gem compilation error

I am trying to install the sqlite3 gem on OSX Mavericks and I have run into an error that seems tricky to get around. By googling, I've not managed to find anyone else with the same problem.

Basically, when I run the gem install command this is what happens:

Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3:
ERROR: Failed to build gem native extension.

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/sqlite3-1.3.9 for inspection.

I don't know what clang is, but gem seems to be passing an argument which is perhaps deprecated or something? Anybody with any more knowledge about this stuff got any ideas?

New version of XCode in Mavericks apparently ships with a compiler that treats unknown passed parameters as errors.

To workaround this issue, set the environment variable to ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future in order to downgrade the error to a warning.

So to install sqlite3 gem:

ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install sqlite3
