pdftk and snow leopard 10.6.2

[Yue-Jun Yin]

Hi,
I installed macports 1.8 for OSX 10.6 and pdftk 1.4 obtained from here 
http://fredericiana.com/2010/03/01/pdftk-1-41-for-mac-os-x-10-6/#comments. 
However I got "fragmentation fault" error when I do cat to combine two 
pdf files as:
pdftk 1.pdf 2.pdf cat output 3.pdf
Could you please help figure out what is wrong?
