HHVM builds failing

Due to this issue. At the time of writing the issue has been fixed and the solution is awaiting merge.

facebook/hhvm#1203

League/event does not use Closure::bind, the referenced PR is already merged and I am not sure if we can say that this package is no longer maintained

[emlynwest]

Since we are switching to the league package I'd say this is not important any more, do we know if the league/event package is hhvm compatible?

Ping @FrenkyNet ?

@WanWizard the league package doesn't use anything funky. Also hhvm and hhvm-nightly are both passing.
