One thing that bothers me, is the fact that portage always erease the directory work to start the compilation. It could verify if this directory already exists and, if is, just enter in the right director and do the make. This will be verry good to people that have problems with a compilation, solve the problem and want to continue it. At now, for example, when you had that problem with kdebase-3.1beta2 on the end of the process, the portage exist and you fix the problem and then you have to compile kdebase-3.1beta2 again!
