Balsa & gnumeric compile problems

[bourne holyfire com (bourne)]

I've some problems with gnumeric 0.19:

-I/usr/local/include -DNEED_GNOMESUPPORT_H
-I/usr/local/lib/gnome-libs/include -I/usr/local/lib/glib/include
-I/usr/X11R6/include  -I/usr/X11R6/include -I/usr/local/lib/glib/include
-I/usr/local/include  -g -O2 -Wall -Wno-unused  -c boot.c

And balsa 0.4.9

.idl file whose stubs you are using. These stubs were generated with an
older version of ORBit, and need to be regenerated."
