Help with making balsa

[Kevin Saenz <kevins auscape net>]

I have gnome-1.0 on RH5.2 and I have installed libPropList-0.8.2
when I configure balsa the program goes through the checking
and makes all the Makefiles. I run make and I get this error message


make[2]: Leaving directory `/root/balsa-0.4.6.2/libmutt'

does anyone know what I need to do to get balsa running?

Thanks
