the other problem is that it is idldir and not idlflags, so you can't
even chain them, but must do them separately:
    
    ORBIT_IDL="`$PKG_CONFIG --variable=orbit_idl ORBit-2.0`"
    AC_SUBST(ORBIT_IDL)
    
    BONOBO_IDLDIR="`$PKG_CONFIG --variable=idldir libbonobo-2.0`"
    AC_SUBST(BONOBO_IDLDIR)
    
    BONOBO_ACT_IDLDIR="`$PKG_CONFIG --variable=idldir
    bonobo-activation-2.0`"
    AC_SUBST(BONOBO_ACT_IDLDIR)
