I have a fresh install of Ubuntu 14.04 on VirtualBox, and I am trying to install YADR (<https://github.com/skwp/dotfiles>), which works really well on Mac OS X. However, after I finished installing and restarted my terminal, the YADR configuration doesn't seem to get applied. Thus, I tried doing

```
source ~/.zshrc

```

Yet I get this:

```
Error: no such file "prezto: old shell detected, minimum required: 4.3.11"
bash: /home/afif/.zshrc: line 15: syntax error near unexpected token `('
bash: /home/afif/.zshrc: line 15: `for config_file ($HOME/.yadr/zsh/*.zsh)
source $config_file'

```

A quick check on my bash --version shows that I actually have GNU Bash 4.3.11.

Anyone knows what's going on?
