I need to be sure the tool I want to use from my app is available to any potential end-user… and if not what do they have to install…
| You can use | 
lsbom
 (
man lsbom
) passing it the path to the package receipt you want to check and piping to a pattern search tool like 
grep
:
 
lsbom /Library/Receipts/Essentials.pkg/Contents/Resources/Essentials.bom |  grep my_tool_name_to_check 
|
or directly using 
grep
 on everything in the receipts folder:
grep -rs my_tool_name_to_check /Library/Receipts/
