使用composer将二进制文件更新到最新版本

I'm using a Laravel package (BrowserShot) that has a dependency on phantomjs. It includes this by stating in composer.js:

"bin": [
    "bin/phantomjs"
],

Doing a composer update installs the phantomjs binary into vendors/bin/phantomjs, but it seems to be an out of date version (1.9.7) instead of (2.0.0).

I can't find any documentation on how to set which version a binary dependency should be using composer.

Is there anyway to do this without having to manually build a new binary and copy it into vendors/bin/phantomjs ?
