The BSD layer is always there.  Basic, portable unix shell scripts are 
always usable, even on a minimal-install machine.  However, there's an 
optional BSD package that adds additional components not required for 
the functioning of the core OS.

If someone has installed the BSD package, there'll be a BSD.pkg bundle 
in /Library/Receipts.
The basic BSD layer comes from the BaseSystem package.  If you want to 
see what files any of these packages install, you can use the 'lsbom' 
command to list the contents of the .bom file for the package, for 
instance,

    /usr/bin/lsbom /Library/Receipts/BSD.pkg/Contents/Archive.bom

 Maybe there's another file whose presence you could use as a sign that 
the components you need have been installed, but I couldn't say what it 
might be.
