On Linux and Windows you can use diffpdf (which differs from diff-pdf mentioned in this thread).
Installing ubuntu using
sudo apt-get install diffpdf
See further this UbuntuGeek page on comparing pds textually or visually .
For Windows , this Diffpdf Windows version works really great. You can download from http://soft.rubypdf.com/software/diffpdf (scroll down to Win32 static version ).
