Yes, I can.
I fixed the first problem with:
sudo pip install matplotlib==1.4.3
With other words, PyPlot is using the system libraries, even though I use a
virtual
conda environment. This is just ignored.
Now everything works fine with Julia 0.3 and 0.4, as long as I do not use
precompilation.
After I did:
Pkg.checkout("PyCall")
Pkg.checkout("PyPlot")
Pkg.build("PyCall")
both libraries get precompiled on 0.4, but now I get the following error:

Any idea?
