Then unless 'grokking Stuff' has a different system, I am not following

... the first branch would be taken, so changing the second branch would 
have no effect.  However, perhaps the rsvg_handle_set_stylesheet is only 
present in the 'librsvg', and not in 'librsvg-bootstrap' (I wouldn't 
expect that as they are the same version, but it could be tested).  If 
so, librsvg-for-system could be used instead, at cost of some rebuilds.
