Update: The author of pdftk, Sid Steward, left the following comment:
A new version of pdftk is available (1.43) that fixes many bugs. This release also features an installer [for] OS X 10.6. Please visit to learn more and download: www.pdflabs.com.This blog post will stick around for the time being, but I (the author of this blog) advise you to always run the latest version so that you can enjoy the latest bug fixes.
OS X Leopard users: Sorry, neither this version nor the installer offered on pdflabs.com works on OS X before 10.6. You might be able to compile from source though. Let us know if you are successful.
Due to my being a remote employee, I get to juggle with PDF files quite a bit. A great tool for common PDF manipulations (changing page order, combining files, rotating pages etc) has proven to be pdftk. Sadly, a current version for Mac OS X is not available on their homepage. In addition, it is annoying (to say the least) to compile, which is why all three third-party package management systems that I know of (MacPorts, fink, as well as homebrew), last time I checked, did not have it at all, or their versions were broken.
Now I wouldn't be a geek if that kept me from compiling it myself. I took some hints from anoved.net who was nice enough to also provide a compiled binary, but sadly did not include the shared libraries it relies on.
Instead, I made an installer package that'll install pdftk itself as well as the handful of libraries you need into
/usr/local. Once you ran this, you can open Terminal.app, and typing
pdftk should greet you as follows:
$ pdftk SYNOPSIS pdftk <input PDF files | - | PROMPT> [input_pw <input PDF owner passwords | PROMPT>] [<operation> <operation arguments>] [output <output filename | - | PROMPT>] [encrypt_40bit | encrypt_128bit] (...)
You can download the package here: pdftk1.41_OSX10.6.dmg
I only tested it on OS X 10.6.2, if you use it on older versions, please let me know in the comments if it worked.
