You could download the installer directly without curl/wget by just pointing your browser to http://thp.io/2014/emojifix/hack-ins...0.10_armel.deb

Of course wget has bit different syntax, but
wget http://thp.io/2014/emojifix/hack-ins...0.10_armel.deb
should do the trick.

Download openrepo mirror as described above.
Not via warehouse neither by terminal installation.
Just download and tap on it (transfer or file browser).
