Ah, OK, I got rid of the first error** with:

case "$target_os" in
 *darwin)
   IS_DARWIN="true"
  ;;
 *)
   IS_DARWIN="false"
  ;;
esac

AM_CONDITIONAL(IS_DARWIN,IS_DARWIN)

The second error is still there.



**why in hell is shell script white-space sensitive ? I've never quite 
understood when it matters and when it doesn't.
