ImportError: zlib not found

[Terrence Brannon]

Hello, I need zlib under Stackless Python (because virtualenv uses it).

import zlib doesnt says 'No module named zlib' under stackless but not under
normal Python.

I have tried this with the 2.6 and 2.52 versions of Stackless on ubuntu (running on virtualbox) with no success:

Hi Terrence,

I guess you build your Stackless python from sources. You may need to
install some devel packages in order to get zlib support within Stackless.

First of all, on a debian based system, you'll need to install this
pakages prior Stackless build.

For example on a debian based system, you'll need libc6-dev
linux-libc-dev zlib1g-dev libxml2-dev libxslt1-dev

Don't forget to build your Stackless python once again when these system
dependencies will be available.

Regards,

Laurent

AHA!!!!! zlib1g-dev is what I needed

Thank you very much.
