Please subscribe to and use the gtk-osx-users mailing list. I’ve CC’d the list for your convenience and to 
get your original questions on the list.

Your seem to be ignoring the very prominent warning on https://wiki.gnome.org/Projects/GTK%2B/OSX/Building: 
Mixing Fink or MacPorts and GTK-OSX will fail.

If you insist on having MacPorts on your system for some perverse reason, the easiest thing to do is to 
create a separate user for gtk-osx; otherwise you’re in for shell hackery to hide the MacPorts paths and 
other environment variables so that gtk-osx can’t see anything that MacPorts installed or built.

The older version of WebKitGtk is because the WebKitGtk folks don’t want to support quartz, so all of their 
anti-quartz ifdefs, most of which are gratuitous simply to prevent WebKitGtk from compiling with quartz, have 
to be patched around. It’s a lot of work and the result is rather brittle, so it has to be redone for every 
version. 1.6.8 is sufficient for GnuCash’s needs so I don’t have much motivation to upgrade for the sake of 
upgrading. 

If you want to build GnuCash with gtk-osx, use https://github.com/jralls/gnucash-on-osx.

Maybe the way you’re passing the html pages to WebKit works in 1.10 but not in 1.6. The gnucash code for that 
is in src/html; maybe there’s something there that can help you sort out why your code doesn’t work. I didn’t 
write that bit and haven’t ever looked at it, so I can’t really offer much more help than that.
