Problem installing IguanaTex on Mac (can't find `.dylib` file) I'm trying to install an experimental version of IguanaTex on my Mac.  I'm stuck and need some help.

Here are the directions:


install AppleScript (IguanaTex.scpt)

mkdir -p ~/Library/Application\ Scripts/com.microsoft.Powerpoint
cp ./IguanaTex.scpt ~/Library/Application\ Scripts/com.microsoft.Powerpoint/IguanaTex.scpt



This worked fine for me.


install IguanaTexHelper (libIguanaTexHelper.dylib)

sudo mkdir -p '/Library/Application Support/Microsoft/Office365/User Content.localized/Add-Ins.localized'
sudo cp ./libIguanaTexHelper.dylib '/Library/Application Support/Microsoft/Office365/User Content.localized/Add-Ins.localized/libIguanaTexHelper.dylib'



This is where I'm having an issue. . I can't seem to find the file "libIguanaTexHelper.dylib" anywhere, and I can't find anything online about it.  I've already made sure that my computer is showing hidden files. 
 Can someone please help me clear this up?
