Title: Output on normal install makes it feel like terrarium hung

I ran an install with fairly standard options, and I thought terrarium had hung on me:

```
$ terrarium install config/ec2_scripts/tpl/pstat/requirements.txt config/ec2_scripts/tpl/pstat/src_requirements.txt config/ec2_scripts/tpl/pstat/dev_requirements.txt
Using real prefix '/usr'
New python executable in /home/wes/.virtualenvs/pstat_446.pEhbjj/bin/python
Overwriting /home/wes/.virtualenvs/pstat_446.pEhbjj/lib/python2.6/distutils/__init__.py with new content
Installing distribute.................................................................................................................................................................................................done.
Installing pip................done.
```

Since I got good feedback on the installation of distribute and then pip, I would have expected at least some kind of feedback on the installation of subsequent packages. Whether that would be one message per package as they were installed, or maybe even just:

"Installing from requirements file requirements.txt......"
"Installing from requirements file src_requirements.txt......"
"Installing from requirements file dev_requirements.txt......"

Also, I set all of the S3-related environment variables, but the install didn't seem to indicate that it was going to use S3. Should there be a `--use-s3`` flag and appropriate logging output, perhaps?
