Hi All,

We are using the 1.8.6 with rails 2.1.1 in our projects, but today I  
need to use the prawn library for pdf generating ( as I researched it  
is mainstream in ruby/rails world for pdf generating), but this line

config.gem “prawn”

in environment.rb doesn’t work with ruby 1.8.6,  
so do you think it will better to use - ruby 1.8.7 with prawn or  
pdf:writer with 1.8.6 (inwardly i prefer second variant)

Regards,  
Pavel
