ImportError: No module named _md5

[JoshuaJ]

When I try to run google's "hello world" example in
GoogleAppEngineLauncher on Mac OS X, I get an error message
complaining "ImportError: No module named _md5".

A similar question was posted here several months ago, and a
workaround was provided, but that one no longer applies; the
workaround has already been incorporated into the latest versions of
GoogleAppEngineLauncher, but I'm still having the problem!

Here's the log that it outputs:

Hi,

If you could provide some more information, that would be helpful:

What version of the SDK are you currently running 1.1.3?
What version of Mac OS are you running?
Are you using the Mac Python install, or a different Python installation when running the SDK?

Thanks,
Marzia

Okay, the OP seems to have gone missing, so I'll take his place. :-)

My app is successfully running under Ubuntu as well as on Appengine
itself. I'm trying to move development over onto my Macbook and ran
into the same problem.

I am running 1.1.5.151

OS X 10.4 (Tiger)

I had to upgrade Pyhton to v 2.5. I did that using Macports.

IIUC, yes. I get the error on my local machine. I'm using Eclipse as
my IDE but I see the same error from that little
GoogleAppEngineLauncher thingie.

This was SO much easier under Ubuntu! :-)

And since Marzia is probably taking a well-deserved rest this weekend, I'll answer the OP's question!

You need to also install py25-hashlib, e.g.

sudo port install py25-hashlib

and you no longer get this error. 

Now, to fix my other errors...
