Hi, after failing with a ruby gems install, I’ve just done a manual  
install of PDF::Writer (including the dependancies: Transaction::Simple  
1.3.0 color-tools 1.3.0) and created the following in a Rails  
controller:

require ‘pdf/writer’

def pdf\_test  
p = PDF::Writer.new  
end

and I get the following error: “uninitialized constant PDF”

Anyone know what the problem is?.. the installs went fine.

I’m on Mac OS X 10.4.5

Thanks, Ray

I’m smelling a path problem on the install. I’m on windows though, so  
path  
issues are differnet, but I also toy with Ubuntu and I’ve been burned on  
the  
path issue a few times.

Hope that helps.
