The function call occurs earlier in the file than the actual definition, and I wondered whether that would be a problem, but when I started up MacVim it all worked fine. In terminal Vim however, I get an error on startup (E117: Unknown function: BuildStatusLn), though it still works fine.

It is not possible to call function before it is defined. You must be mistaking about when this function gets called. If you have something like

    set statusline=%!BuildStatusLn()

then function *will* be called when statusline is drawn, but it is not called *when this line is parsed*. I guess that in MacVim statusline draw is deferred until gui initialization (which happens after vimrc loading) and in terminal it is drown immediately when you set this option.
