Is there some way to have the code check whether the API exists and
"exit gracefully" if it does not?  e.g.:

guile> (defined? 'gnc:restore-report-by-guid-with-custom-template)
#f
guile> (defined? 'car)
#t

So you could only call the API if it's defined?  That way you wouldn't
require changes to 2.4.
