LSP Routine doesnt run in CIVIL 3D

[BoarsNest01]

I have a .LSP routine that I have used in Land Desktop that is not working in CIVIL 3D. When running the .LSP it displays the error: "no function definition: F:BEAR".
Any ideas?

There's a line in the lisp:
(setq brng (f:bear pt1 pt2 "%%d"))

That requires a separate 'defun' named "f:bear: that doesn't exist with this routine. It must have been loaded separately when this routine did work. Maybe it was loaded by "acad.lsp" or "acad2008.lsp" that doesn't now get loaded because of a change to the startup process or files.
