Pkg.add("Ijulia") chmod not defined - julia

Question

Newbie trying to get going with IJulia on Debian Jessie, and am stuck with an error. Don't know how to interpret the message, and not actually sure on what to do next.
The beginning is all ok :

Then I get a "chmod not defined" error :

end

So, what shall I do next ? chmod a+x build.jl ? then Pkg.build("IJulia") ?

Conda.jl author here. I do not have enough reputation to comment, so here is an answer.
Conda is tested on the latest julia 0.3, which is 0.3.12, and works there. So a possible fix would be to update your Julia version to either that or 0.4.
You can also try to install it manually, by making it executable and then running ./installer.sh -b -f -p $HOME/.julia/v0.3/Conda/deps/usr/.
