Well, we had that, but the problem wasn't old .so in the install directory but that someone removed a module without bumping the api version. If that was done (I did it later to fix the problems) then the left over woud just be ignored. But you are right, those things _can_ happen, so let me add another case when it makes sense to delete build/ and the install dir: when strange bugs occur. :-) [...] > > make -j install > > Yep, that's what I do in the "dorebuild" script.
