Has anyone seen this error before?

[mboersma]

I wonder if this change deis/docker-go-dev@8f53864 has something to do with it. We were worried that changing the base image might omit some tool that was expected, but it has worked everywhere else...

[bacongobbler]

Indeed I think that may be the issue as well. I'm downgrading this PR to 0.19.0 to see if there's any difference.

[bacongobbler]

Yep, that was it. Gonna roll with 0.19.0 for now and file an issue.
