remove deprecated flag

[epequeno]

From the man page for virtualenv:

--distribute
      Ignored.  Distribute is used by default.

This is news to me!

Well, the current master and virtualenv --help says something different!

  --distribute, --use-distribute
                    Use Distribute instead of Setuptools. Set environ
                    variable VIRTUALENV_DISTRIBUTE to make it the default

Probably @epequeno is running Python 3. There is no setuptools, so distribute is default of course.

Odd, I have virtualenv 1.7.1.2 and python 2.7.3. I still get the same message with virtualenv --help

[kennethreitz]

Hmm, i'm not seeing it either on v1.7.2. Reverting.

Hmm, does this no setuptools change with Python 3?

Sorry, I can't help; I'm new to Python. ;) I simply noticed the difference while diving deeper and identified that there's no issue for it yet.

Thanks for doing this tutorial though - it helped me to get started (as in: baby steps). :)
