Try running the "common_startup.sh" script in the scripts folder (/opt/galaxy/scripts/common_startup.sh) before you restart. This way all required dependencies will be installed using the custom galaxy pip version.

Also, you might want to consider upgrading your python version, as 2.6 is nearing deprecation (very) fast.
