Picture this common scenario, which I saw during installability
testing - you install hledger to try it out. Cabal builds it with
process 188.8.131.52. You get enthusiastic and later try to cabal install
hledger-X, but this fails ("can not install hledger-X because hledger
(In other, similar-seeming cases I have seen cabal rebuild the
installed depender; I don't understand all of cabal's behaviour.)
I presume the user could work around this by
- ghc-pkg unregister hledger; cabal install hledger-X
- installing hledger the first time with --constraint process-184.108.40.206
but I figured a low-impact to make things "just work" was to bump
hledger's process dependency.
Is it making sense ? I welcome further insights or better solutions.
