ImportError: No module named blinker

Hi, I just installed Tipfy for the first time and I am getting an error.

Anyone see anything glaring at them? thanks.

I've had similar issues before. 

When you do the tipfy installation it installs blinker, jinja, and werkzeug to ./project/lib/dist.  If the files are there and in site-packages it gets upset for some reason.  My "gotta get stuff done" solution was just to uninstall the modules in site-packages (I was using pip).  I haven't researched further to figure out why it happens.

Ok, thanks, calvin.  You mentioned the lib/dist directory so I looked and there was no blinker directory or egg, just: babel, jinja2, pytz, tipfy, tipfyext, werkzeug and wtforms.  So I started playing with the tipfy/app.py file and suddenly 'Hello, World!' appeared.  funny.  I had been installing stuff left and right so like you said I must have installed something that made tipfy unhappy somehow.  But it's working now.
