Well, it cannot work for clang in Xcode 5.0.x... so I see no contradiction here. > You somehow still have the compiler_wrapper from fink-0.36.4; I did nothing fancy to update, just a "cvs up" followed by a "fink update-all". If it happened for me, it is highly likely to happen for other people, too. Aha, and looking at the code, that's pretty much guaranteed to be the reason: Because unlike a "fink selfupdate", this process does *not* restart fink after updating fink. So this happens: * fink rebuilds fink * fink installs the new fink.deb; the postinst script is triggered, which removes the clang wrapper * the old fink is still running and updates some other package * this recreates the "old" wrapper. So this would have been avoided if I did run "fink selfupdate". But there might be other ways to trigger this or similar breakage. Hence I think it would be preferable if things were arranged in a way that such problems are impossible by design. So, why don't we simply re-create the wrapper each time we start a build process? Of course, care must be taken to not affect concurrent build processes... but this could be achieved by creating per-package wrappers on the fly for each build. That shouldn't be too hard. E.g. when preparing the build, we create %b/../bin/clang etc. and then add this to the build-time PATH, just like we add %p/var/lib/fink/path-prefix-clang/compiler_wrapper Hmm, that said... why exactly are those wrappers not part of the .deb to begin with? That would be even simpler, wouldn't it?
