Installing PDFtk Server edittion on your Mac

This workaround install is necessary because PDFtk was pulled from homebrew-cask due to issues with it aggressively overwriting file permissions that could impact other installed libraries. See this homebrew-cask issue.

The following steps worked on Mac OS X 10.10.1 with a standard brew installation for the PDFtk Mac OS X server libary version 2.02.

All Terminal commands separated by a full line space. Some commands wrap into multiple lines.

Download and extract the Mac OS X server install pacakge
