For those interested, it turns out the error is caused by JuliaParser.jl, 
and has been fixed in master. If you run Pkg.checkout("JuliaParser") you'll 
still see a bunch of deprecation warnings but eval etc. seem to work fine.

I'll probably do some work on supporting 0.4 fairly soon.

Thanks everyone, I reinstalled as advised by Ivar, and everything works. 
This is really rather wonderful :)

Hi Thomas,

I've decided to wait until 0.4 has settled down a bit before supporting it 
in Juno, so it's best to grab the latest release of Julia (v0.3). Building 
from git should work fine but you could also try using the Ubuntu packages 
 if 
that's not working for you.

Re: [julia-users] Re: JUNO: Couldn't Connect to Julia

[Ivar Nesje]

To be clear on the exact commands Keno referenced. This is the steps you 
need to perform.

git clone git://github.com/JuliaLang/julia.git
git checkout release-0.3
make cleanall
make

If you want to further reduce the risk of getting a broken commit (someone 
might do a incomplete or broken backport), you should checkout the latest 
tagged release. (now it is v0.3.1)

When you clone from github, you will always get the master version (as long 
as we don't change our github settings, and that would be somewhat 
unusual). One might reasonably argue that we should have used a dev branch 
to test the breaking changes for unintended breakage, before merging them 
back to the master branch, but currently we don't have the resources to 
maintain multiple branches. That would be quite tedious work.

You can either check out the release-0.3 branch or use the
juliareleases (as opposed to julianightlies) PPA as described at
http://julialang.org/downloads/

[Nils Gudat]

Hi Thomas,

Not sure about your particular error, but when I installed mine it didn't 
work due to an outdated Jewel package (apparently Julia came with an older 
version). Pkg.update() did the trick. Since you get a couple of 
Jewel-related errors in your output this might be worth trying. 
In general, the developer of Juno is super helpful and you can approach him 
with your specific issue on the Julia-LT Gitter 
.

Best of luck!

[julia-users] Re: JUNO: Couldn't Connect to Julia

[Thomas Moore]

Well that was another surprise: to upgrade, I deleted my julia and .julia 
files, and then I just went to the github site 
 and followed the installation 
instructions there (in particular, running git clone 
git://github.com/JuliaLang/julia.git and then "make".

I wasn't expecting a 0.4 dev version. How would one go about installing a 
0.3 version on Linux?
