I’d start with downloading the latest Julia release (which is v0.5 at the moment) from [the official site](http://julialang.org/downloads/). Julia v0.4 is quite outdated now.
If this doesn’t automagically resolve the problem, try installing `libz` as indicated in the error. E.g. on Ubuntu you can run:
```
sudo apt-get install zlib1g-dev
```
from a terminal.
