You are welcome! You should try to compile the most recent code which is
in the gchemutils cvs tree. gchempaint is not anymore developed as a
separate project, so the HEAD gchempaint branch is unmaintained. 0.9.0
is also a bit old, many things have changed since then.
If you have any issue compiling gcu HEAD, please let me know, there are
so many experimental features that this might happen.

About the curved arrows, I agree it is an essential feature (I really
need them), but I intended to first replace the canvas used by
gchempaint. My idea was to wait until gtk+ includes a canvas, but
although the point has been discussed for a long while, there is still
nothing, so I (we?) might have to develop a simple cairo based canvas
for gchempaint.
If you prefer to implement the curved arrows using the gnome canvas, it
is still possible, but I'd like that rendering be made using cairo
instead of libart.

Thanks for your interest,
Jean
