$ FONT_PATH='/Users/Plutonist/Downloads/130406-thin-line-ui/font/Flaticon.ttf' pod update Iconic
[!] The `Iconic` Pod is not installed and cannot be updated
```

The error output:
`[!] The 'Iconic' Pod is not installed and cannot be updated`

So I add `pod 'Iconic', '~> 1.0.0-beta3'` to Podfile.

But the install progress is stuck at `Installing Iconic (1.0.0-beta3)` line and no longer continue.
