Re: Trouble installing mirage from OPAM

[Anil Madhavapeddy <anil@xxxxxxxxxx>]

Our constraints are all over the place, due to the development remotes
getting out of sync.  I've just fixed the Jenkins server (which ran out
of inodes), and the constraints now, and then a full test run will give
us a working version.

I've also switched mirage-www over to use Mirari now, which simplifies
the application build scripts dramatically.

Update shortly once all these builds are finished and packages are
pushed...
