solaris compile problem .9.3

[Paul Laiming <plaiming agere com>]

i've been trying to compile balsa .9.3 version and i am 
getting the below compile failure. i have helix gnome
and libPropList installed. i am running solaris7 on ultarsparc.
anyone have any idea why i am getting this fail. i can't seem
to find the variables in any of the files so i don't know if
i need to go in an define them or what?
anyone have any ideas?

thanks,
paul
