Balsa compile

[Ross Schulman <ross brandeis edu>]

I'm getting the following error when trying to compile balsa 0.4.5. 
Does anyone know where gnome.h is supposed to be and what package its
in?  It isn't anywhere on my system.

gcc -DHAVE_CONFIG_H -I. -I. -I.. -I. -I../src -I.. -I/usr/include
-DNEED_GNOMESUPPORT_H -I/usr/lib/gnome-libs/include -I/usr/X11R6/include
-I/usr/lib/glib/include -I/usr/X11R6/include -I/usr/lib/glib/include -g
-O2 -Wall -Wmissing-prototypes -Wpointer-arith -c libbalsa.c
libbalsa.c:23: gnome.h: No such file or directory
In file included from libbalsa.c:24:
../src/balsa-app.h:22: gnome.h: No such file or directory
