I'd recommend reading the discussion here: http://stackoverflow.com/questions/91846/rails-or-django-or-...
Some great back-and-forth that may help illuminate your decision.
(I assume you're talking about Rails vs. Django, but Python has some lighter-weight frameworks that can speed up development. Ruby may too, but I'm not as familiar.)
That's simply not true, and I wonder why you think it is.
Setting up Passenger Phusion is snake simple, and deploying could not get any easier ("cap deploy", as one example).
You can also run your app using JRuby and deploy it to any standard Java app server as a war file. (Using JRuby gives you other benefits as well, such as speed and connection pooling, plus the use of every Java library.)
"Is it easier to find ruby people or pythoners?"
I've had trouble finding Ruby devs. And while I've never tried to find a Python developer I get the impression there are fewer Python devs in my area (Phoenix, AZ, USA) than Rubyists. When I talked to some people about trouble finding devs I was told it's a similar problem looking for Java or C# or PHP people.
#ruby-lang on freenode is a great place to get help. #rails, maybe not so much, though I'm basing that more on hearsay and comments from people I know. OTOH, #ramaze rocks, and would be my first choice for any new Web app. Less ceremony, full-featured, great + friendly community.
Bottom line, though, is that you should spend some time with each language, look at a few Web frameworks, and pick what makes you feel most comfortable.
I tried Django in my early coding days, and I liked it at first. I tried Rails and switched immediately. I think it was the fact the Django used mostly Regular Expressions for routes, and Rails wasn't so over sophisticated. The pythonic semantics Django uses just seemed awkard to me when I was a beginner, and the ruby way Rails used seemed a lot easier to pickup.
If you are looking for community members, both ruby and python have large amounts of users, and active irc, as does both Django and Rails. Rails does seem to be more actively developed(to me) than Django. Django hasn't had a major release since v1.0.0, and Rails is on version 3.0.5.
That's just my 2 cents. Whatever you like better, and whatever fits the job, I would go with that one.
