bash: warning after install all files to home directory

Hello, thanks for your lib. From time to time I have warning, for example:

```
➜ git pull
bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
```

```
➜ uname -a
Linux homestead 3.16.0-23-generic #31-Ubuntu SMP Tue Oct 21 17:56:17 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
```
