I've tried installing version 2.2.9 from source. Configure stopped with the message that GLIB 2.6 wasn't present. I tried to install GLIB 2.6 from source and make crapped out with errors. I seemed to successfully install GLIB 2.6.5 (well, configure, make and make install all ran) but when I try configure with Gnucash, it still tells me that GLIB 2.6 isn't installed.
Am I going to have to install the Gnome desktop to get it working?
