The problem here is the following: How do you know before the src_install phase, that a package has no ABI-specific content? And even, if you know that, how would you define the dependency part?

Since my work with multilib-portage started in 2009 and is still not in the PMS, also i tried to keep it simple, i would not even try to guess an ETA for both of your, in my eyes more complex, ideas. ;-) I of course wont prevent you from preparing them and getting them in, they may be nice, especially removing the need to recompile already compiled code. Just dont underestimate the work with it. -- Thomas Sachau Gentoo Linux Developer
