# 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](https://github.com/caskroom/homebrew-cask/issues/7707).

###### The following steps worked on Mac OS X 10.10.1 with a standard [brew](http://brew.sh/) 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

```
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
```

### Now create directories for where it would go with a proper brew install.

*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`

### Give the `Payload` file the proper gzip file extension and unzip it

```
mv ~/Downloads/pdftk_package/pdftk.pkg/Payload ~/Downloads/pdftk_package/pdftk.pkg/payload.gz
```

```
gunzip ~/Downloads/pdftk_package/pdftk.pkg/payload.gz
```

### Use `cpio` to unarchive the resulting file

```
cd ~/Downloads/pdftk_package/pdftk.pkg/ && cpio -iv < ~/Downloads/pdftk_package/pdftk.pkg/payload && cd ~
```

### Move the relevant extracted files to their appropriate locations within the `Cellar/pdftk` directory

```
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
```

### Create the appropriate symlinks through `brew`

`brew doctor`

and most likely then

`brew link pdftk`
