I want to set up a jekyll blog on a shared server. When I try to install Jekyll I get "You don't have write permissions". How do I fix this without root or sudo?

More detail:

I have space on a shared server and don't have root access. I couldn't install Ruby, though the hosting company installed it upon my request. 

When I try to install Jekyll I use 

```
user@hosting.org [~]# gem install jekyll

```

and this is the response I get:

```
ERROR:  While executing gem ... (Gem::FilePermissionError)
You don't have write permissions into the /usr/lib/ruby/gems/1.8 directory.

```

I have seen different suggestions for changing the GEMPATH which I have tried including 

```
export GEM_PATH=/home/user/something

```

But even after doing so 

```
gem env 

```

still results in 

```
GEM PATHS:
- /usr/lib/ruby/gems/1.8
- /home/user/.gem/ruby/1.8

```

Any tips? Is it possible to install jekyll without root or sudo priviliges or am I just making some rookie PATH error?
