That's great, thanks.

Terrific, thank you.

You should be able to install it; if you add libicu-dev to the
packages stanza in .travis.yml it will put it in there.

However you seem to be using pkg-config, which Ubuntu 12.04 LTS (which
travis currently uses) doesn't provide for libicu. 14.04 LTS does, and
it's possible to use that as a beta with travis, I think by changing:

sudo: false

to:

sudo: required
dist: trusty

That will run about a minute slower than the current builds, but
that's not a huge problem for the volume we're dealing with. I'd hope
that they move 14.04 out of beta soon (at which point it should be
possible to use with container builds, which are faster), since 12.04
only has support until next year.
