[Distutils] Not installing the install_requires

[Peter Bengtsson]

Crap!
That didn't work either!
IOError: [Errno 20] Not a directory: '/home/peterbe/virtualenvs/
djangopeoplenet/lib/python2.5/site-packages/premailer-1.2-py2.5.egg/
premailer/version.txt'

This must be because of some egg magic that I don't understand.
What I did was this (in premailer.py):

__version__ = open(os.path.join(os.path.dirname(__file__),
'version.txt')
                   ).read().strip()

That works if the thing is installed.
But not when trying to use it as an egg.

I tried to read P.J Eby's reply regarding using execfile() but it went
over my head.
