In order to get "make menuconfig" work, you need to manually hack the
makefile and add "-lncurses" to link flags, at least here it worked
fine.

sure! I missed "checkout" (co) keyword... however you missed "-" in
"-d:pserver..." :-)

Line is:

cvs -d:pserver:anonymous at anoncvs.enlightenment.org:/var/cvs/e  co e17

I never played with embryo and I'll restrict its use to basic theming
helper, for development it will be either C or Python (I've done
python bindings, in e17/proto/python-efl).

Yes, it will be possible, there is "GEvas" that embed Evas as a GTK
component. Yet, I'd like to write a "fullscreen" applet that itself
embed other evas components, then you'd benefit from canvas power, as
overlapping/semi transparent elements... it will be more
gdesklets/superkaramba like.
