Lucrative is a new anonymous cash project (yes, another one and we're still waiting to hear a peep out of OpenDBS; hint Ryan) but it's there anyway. These projects can generally be classified pretty grossly and Lucrative is based on Lucre, but I can't remember the classification of Lucre.
It seems that Intel have really tried with their compiler (non-freespech but free-beer for non-commercial) and make it a GCC drop-in. It can't compile a kernel without a fair amount of bodges, but I managed to get portage to use it and it compiled a number of packages perfectly. I just need to benchmark them now.
