rgeo upgrade to 0.3.20 in rails 4.2.2 -NoMethodError: undefined method `point' for

I just updated my rails application to 4.2.2 and therefore I did also update the rgeo gem to 0.3.20

I ran in the following error:

NoMethodError: undefined method `point' for nil:NilClass

So I digged into the rgeo lib and noticed that the factory generator in rgeo returned nil in rgeo/geos/interface.rb

You can check it in irb

2.2.1 :001 > require 'rgeo'
 => true 
2.2.1 :002 > RGeo::Geos.supported?
 => false 

So you wanna make sure that you have the GEOS lib installed. I solved it via brew brew install geos and installed rgeo again and finally it worked
