Hi there,
This looks like an installation problem with YAJL, rather than Visage itself.

Can you please open up the ticket there, and let me know what the issue number is in this issue?

[ssm2017]

i could not find an issue queue for the link you have showed me but the author is speaking in the readme file about a parent project where i reported the issue.
here is the link : lloyd/yajl#91

Oops, I linked to the wrong project. :-(

I meant to link to yajl-ruby.

No activity. Closing.

P.S. I'm thinking about producing RPMs and debs with Omnibus, which would hopefully eliminate this class of problem.
