Installing Mercurial on Mac OS X 10.6 Snow Leopard

I installed Mercurial 1.3.1 on Mac OS X 10.6 Snow Leopard from source using the following:

cd ~/src
curl -O https://www.mercurial-scm.org/release/mercurial-1.3.1.tar.gz
tar -xzvf mercurial-1.3.1.tar.gz
cd mercurial-1.3.1
make all
sudo make install

This installs the site-packages files for Mercurial in /usr/local/lib/python2.6/site-packages/. I know that installing Mercurial from the Mac Disk Image will install the files into /Library/Python/2.6/site-packages/, which is the site-packages directory for the Mac OS X default Python install.

I have Python 2.6.2+ installed as a Framework with its site-packages directory in:

/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages

With Mercurial installed this way, I have to issue:

PYTHONPATH=/usr/local/lib/python2.6/site-packages:"${PYTHONPATH}"

in order to get Mercurial to work.

Questions

  • How can I install Mercurial from source with the site-packages in a different directory?
  • Is there an advantage or disadvantage to having the site-packages in the current location? Would it be better in one of the Python site-package directories that already exist?
  • Do I need to be concerned about virtualenv working correctly since I have modified PYTHONPATH (or any other conflicts for that matter)?
