I stumbled upon Agar yesterday, and from the description and screenshots I
think
it is exactly what I have been looking for. However, so far I have been unable
to do anything with it.
Agar 1.4.1 won't build (linux x86_64/gcc 4.6.3), make depend runs fine, but
make
all fails with the following errors:
