Getting peewee to work on elastic beanstalk - amazon-web-services

Question

I'm trying to install the peewee package on an elastic beanstalk instance to control a bottle application. I think the problem is with the MySQL-python dependency, but peewee doesn't load either. My requirements file looks like this:
bottle==0.11.6
peewee==2.1.1
MySQL-python
I also tried MySQL-python as MySQL-python==1.2.4b4. For a number of reasons which I believe are summed up here, this doesn't work; peewee isn't installed and I get this error message in the log:
2013-05-18 06:57:08,407 [INFO] (15947 MainThread) [directoryHooksExecutor.py-29] [root directoryHooksExecutor info] Script succeeded.

So pip doesn't work for these packages. I'm pretty sure I could fix this by connecting to the EC2 instance and installing MySQL-python without pip, but it seems to me that would defeat the purpose of elastic beanstalk, since every time a new instance started it would need me to go in and tinker with it manually. Is there a proper way for me to deal with this problem? I've also had the same issue trying to install things like scipy and matplotlib, so broadly, is there a way I can install python packages on elastic beanstalk instances without pip, and without going into each instance individually? Should I be looking into how to make a custom AMI and use it on beanstalk?
Thanks a lot,
Alex

Sorry I forgot I asked this.
I eventually solved this issue by ssh'ing into the instance and installing MySQL-Python using easy_install instead of pip.
Basically I went to the python virtual environment direction at:
opt/python/run/venv/bin
and installed version 1.2.3 using easy_install:
sudo ./easy_install MySQL-Python==1.2.3
I checked to see it was installed by trying to import MySQLdb in the virtual environment's python:
./python
>>>import MySQLdb
>>>
and it worked for me. Then I reset the server by pushing to it again with the elastic beanstalk command line tool:
git aws.push
and that's about it. Somewhat annoying to have to do it, but it seems to continue to work when a new instance is started up.
Thanks,
Alex
