Problems installing IJulia with Julia 0.4 on Ubuntu

[rdeits]

I've been trying to install IJulia with Julia 0.4 on Ubuntu 14.04, but I've been unable to get it to work. Attempting to run:

Pkg.add("IJulia")

gives:

INFO: Building IJulia

I've purged julia, deleted ~/.julia, and all the julia-related files from .ipython, and reinstalled julia 0.4 from the staticfloat PPA, and I'm getting the same result.

After this failure, I can complete the build, by restarting Julia and running Pkg.build("IJulia"). However, the installation doesn't actually seem to be functional. Running notebook() gives me the jupyter web interface, and I can create a new Julia 0.4 notebook, but executing any cell in that notebook just results in no output whatsoever from the kernel.

As additional info: I can successfully install IJulia on Julia 0.3, but I still get no response from the kernel. Here's what the output looks like:

Any advice or suggestions? I'm happy to help try to debug this, but I'm not really sure where to start.

Dup of JuliaLang/julia#13915 and JuliaLang/julia#13200. The workaround is to just try again.
