No, it looks like they just bumped the version from 1.99.1 to 2.99.2.  
There's probably more to it than that.  Anyway, 1.99/2.0 appears to be 
history, and it will be 2.99/3.0 from here on.

What I'm looking at is using AC_ARG_ENABLE to make a --disable-gda 
argument, so that for the gda-dev branch (at least for now) building the 
gda backend would be the default.

This would replace the current argument which takes a path to the 
libgda-2.0.pc file.  Shouldn't that be set in the PKG_CONFIG_PATH 
environment variable?

What I don't understand is:
When I pass --disable-gda, how does make know not to build that backend?
For example, I don't pass --enable-sql, and the postgres backend is not 
built. (Right?  It's got to be right; I don't have postgres installed on 
some machines where I've built gnucash.)  But I can't seem to find how 
that information is passed from configure to the build process.

The build succeeded with the above stop-gap.  I was able to open an 
existing db, and my transaction and accounts were there.  Now, to really 

If anyone is interested, libgnomedb was also bumped up to 2.99.  It 
requires gtk+ version 2.10.x, but their configure tests for an older
