I propose two solutions: * Fix the dependency resolver * Add support in Cabal and Hackage for suggested version constraints
Simon PJ just came up with a suggestion for the second part. The idea is this:
If we see a dependency like "base >= 3" with no upper limit, we should satisfy it with base-3 in preference to base-4, on the grounds that the package is much more likely to build with base-3. This seems to be a solution that works without any magic shims or "preference files" or anything else.
Choose the lowest available version that satisfies all of the constraints? -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
