Not all cycles are solvable w/in the domain of execution which is an unfortunate fact. This loops back into why jstubbs was after use dep cycle breaking (fair bit more fine grained of an issue), a discussion that thus far has been ignored, and the usage of the build flag. > > SRC_UNPACK_DEP="app-arch/unzip" > > SRC_COMPILE_DEP="dev-scheme/bigloo" > > SRC_INSTALL_DEP="" > > Labels are a cleaner solution to this.

I know, but I'd rather not have the notion "labels solves all" pushed forth w/ out people knowing what it is, please. thanks, ~harring
