MacPort deployment

[IT]

Hi,

I have installed pdftk Macport in my administrator computer. Now i  
want to deploy the binaries and all related files to run pdftk on 20  
networked macs without copying all /opt directory. Please, anybody  
can advice me about the best way to deploy a MacPort from the  
administrator computer to users computers ? Is there a way to make a  
osx package from an installation for deployment ?

thanks in advance
