Hi everybody, I fail to remember or re-google the package version selection for cabal, if no version constraints are given. If I depend on "iteratee", and there are no constraints, does it take the lowest version? When I pushed the newest version of the RNAFold package, the log showed iteratee-0.1.0 to be used, which failed of course: http://hackage.haskell.org/packages/archive/RNAFold/1.99.1.0/logs/failure/gh... It got really weird, however when I saw that the dependency BiobaseVienna-0.2.2.3, which is the one actually using iteratee, was built correctly. Of course, seeing the error of my way, I have started adding more version constraints to every package I maintain. Gruss, Christian
