opam install vchan failed

[Phiho Hoang <hohoangphi@xxxxxxxxx>]

Dear List,

I am trying to install 'vchan' as described here http://openmirage.org/blog/

and got this:

$ opam install vchan

vchan is not a valid versioned package name

'opam install vchan' failed.

It is much appreciated if someone would advise the correct package name for vchan.

Regards,

PhiHo
