MCEdit is an open-source, BSD-licenced world editor for the viral indie hit Minecraft.

First, read the Reporting Guidelines before submitting any issues; there's even an easy link to create a GitHub issue on that page.
Consider checking the MCEdit site and trying the development version. It's possible that your issue may have already been fixed and is waiting for a stable release.
MCEdit is written in Python using a variety of open source modules. When developing it is recommended to use virtualenv to keep dependencies sane and for easy deployment.
Development Quick Guide
You'll need Python 2.6+ and
pip at a minimum before getting started. This quick guide assumes a unix-y OS.
git clone https://github.com/mcedit/mcedit cd mcedit git submodule init git submodule update
Optionally (but highly recommended), setup and activate virtualenv. virtualenv will simplify development by creating an isolated and barebones Python environment. Anything you install while virtualenv is active won't affect your system-wide Python installation, for example.
easy_install virtualenv virtualenv ENV . ENV/bin/activate
Install various dependencies. This may take a bit (especially numpy). If installing pygame errors, try installing from a binary packages or following one of the guides from that page to install from source.
easy_install PyOpenGL easy_install numpy easy_install pygame easy_install pyyaml
You should now be able to run MCEdit with
python mcedit.py assuming you've installed all the dependencies correctly.
"Freezing" Python applications to deploy them for use by non-technical users is not in any way fun, expect errors and edge cases.
Additional dependencies are required to package MCEdit. Regardless of which platform you're targetting, esky will be required.
Note: These instructions have only been tested on OS X Lion.
You will run into errors attempting to use the system Python when packaging anything under OS X. The easiest way to install a new Python is by using Homebrew.
If you were using the system python while developing and using virtualenv, you'll need to overwrite it with your newly installed version.
brew install python virtualenv -p /usr/local/bin/python ENV easy_install esky easy_install py2app python setup.py bdist_esky
This will leave you with a zip file in
dist/ that contains a portable
