[StarCluster] error when starting starcluster

[Justin Riley]

Hi Marcin,

After some quick googling I found that this error is caused when Python's built-in socket module wasn't compiled with SSL support. Here's a link to someone else having the same error with boto on stackoverflow:

http://stackoverflow.com/questions/877072/httpsconnection-module-missing-in-python-2-6-on-centos-5-2

In short you basically need to recompile Python 2.6 with SSL support. Here's a link to a slightly older doc that does this for python 2.5 on CentOS 5.1:

http://agiletesting.blogspot.com/2008/05/compiling-python-25-with-ssl-support.html

Unfortunately this is not something StarCluster or boto can fix by way of code. Either the Python install has SSL support or not. However, boto could do a better job of checking for SSL support and raising an exception with a better error message instructing the user of the *real* problem (Python install not compiled with SSL support). I've filed a bug report about this on boto's issue tracker:

https://github.com/boto/boto/issues/249

If I get some time I might try to hack this in myself.

Hope that helps,

~Justin
