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.
curl -o ~/Downloads/pdftk_download.pkg https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/pdftk_server-2.02-mac_osx-10.6-setup.pkg
pkgutil --expand ~/Downloads/pdftk_download.pkg ~/Downloads/pdftk_package
*NOTE: I had no prior install of PDFtk via brew-cask when doing this. Not sure how having multiple versions installed might affect brew link
and these instructions.
cd ~ && mkdir /usr/local/Cellar/pdftk /usr/local/Cellar/pdftk/2.02 /usr/local/Cellar/pdftk/2.02/bin /usr/local/Cellar/pdftk/2.02/lib /usr/local/Cellar/pdftk/2.02/share /usr/local/Cellar/pdftk/2.02/share/man /usr/local/Cellar/pdftk/2.02/share/man/man1
Here are the individual directories being created above (assume being in cd ~
directory).
mkdir /usr/local/Cellar/pdftk
mkdir /usr/local/Cellar/pdftk/2.02
mkdir /usr/local/Cellar/pdftk/2.02/bin
mkdir /usr/local/Cellar/pdftk/2.02/lib
mkdir /usr/local/Cellar/pdftk/2.02/share
mkdir /usr/local/Cellar/pdftk/2.02/share/man
mkdir /usr/local/Cellar/pdftk/2.02/share/man/man1
mv ~/Downloads/pdftk_package/pdftk.pkg/Payload ~/Downloads/pdftk_package/pdftk.pkg/payload.gz
gunzip ~/Downloads/pdftk_package/pdftk.pkg/payload.gz
cd ~/Downloads/pdftk_package/pdftk.pkg/ && cpio -iv < ~/Downloads/pdftk_package/pdftk.pkg/payload && cd ~
cd ~ && mv Downloads/pdftk_package/pdftk.pkg/bin/pdftk /usr/local/Cellar/pdftk/2.02/bin/pdftk && mv Downloads/pdftk_package/pdftk.pkg/lib/* /usr/local/Cellar/pdftk/2.02/lib/ && mv Downloads/pdftk_package/pdftk.pkg/man/pdftk.1 /usr/local/Cellar/pdftk/2.02/share/man/man1/pdftk.1
Or the individual file moves (assume being in cd ~
directory)
mv Downloads/pdftk_package/pdftk.pkg/bin/pdftk /usr/local/Cellar/pdftk/2.02/bin/pdftk
mv Downloads/pdftk_package/pdftk.pkg/lib/* /usr/local/Cellar/pdftk/2.02/lib/
mv Downloads/pdftk_package/pdftk.pkg/man/pdftk.1 /usr/local/Cellar/pdftk/2.02/share/man/man1/pdftk.1
brew doctor
and most likely then
brew link pdftk
Can double that. M1 and brew install pdftk-java works.
