Uhh .... like you need to look in the file that has those functions undefined.

Look for the #ifdef that is around them.  Then edit config.h to reflect whether
that item should or should not be defined.  (It's been 6 months since I've 
compiled it, so I don't remember what it is .. but it's in there)

Do what I said above, and you're life will be one of blissful use of elm that
works happily.
