Compilation Errors on Travis (for R package)

I have an R package that imports feather. Builds on Travis are failing due feather failing to compile. Any ideas how to correct?

Here’s the set of errors:

* installing *source* package ‘feather’ ...
** package ‘feather’ successfully unpacked and MD5 sums checked
** libs

So you have to install gcc-4.9 or greater and set CXX1X, CXX1XSTD in ~/.R/Makevars, e.g.

https://github.com/jimhester/rio/blob/9026180fd731aaed34f21cba3b5e207124618e5b/.travis.yml#L8-L20

Which allows you to build successfully, https://travis-ci.org/leeper/rio/builds/131807863#L1367-L1380

This is pretty painful, but I am not sure what can be done to avoid it unless travis updates their default gcc or ubuntu version…

also here, FYI, just setting dist=trusty solves the problem, though I am not sure whether this is recommended.
