I've stumbled on this error when trying to install a easyshop buildout:

Exception: No SSL support found
An error occured when trying to install ssl-for-setuptools 1.10.Look above this message for any errors thatwere output by easy_install.
While:
  Installing instance.
  Getting distribution for 'ssl-for-setuptools'.
Error: Couldn't install: ssl-for-setuptools 1.10

After scratching my head for a while, I've found the solution:

# apt-get install libssl-dev
