Hi Hayato,
I'm sorry but yes gnome-build version is the source of your problems.
What is your distribution?
If you want you can try to change the required version in my
configure.ac script and then rebuild.
Just change the line 32 from:
GNOME_BUILD_REQUIRED=2.23.90
to
GNOME_BUILD_REQUIRED=0.2.4
and then rerun ./autogen.sh
But to do so you have to compile vtg from the svn archive since
autogen.sh isn't included the the distributed tarball.
So you can get the source with the svn command:
svn checkout
http://vtg.googlecode.com/svn/trunk/ vtg-read-only
Moreover I *can't* guarantee that vtg can work with gnome-build 0.2.4
since I only tested with 2.23.90
Have a nice day,
Andrea
