598	Bogus build failures on HackageDB	mboes		"HackageDB reports build failures for packages due to inconsistent dependencies. For instance, the dedukti package currently has a build failure because it depends on both bytestring and text. The latest version of bytestring is 0.9.1.5, but text is built using bytestring-0.9.1.4. This causes a build failure because the functions in text expect as arguments something of type ByteString from bytestring-0.9.1.4, not something of type ByteString from package bytestring-0,9.1.5.

If the text package were built using the latest available version of bytestring, as would happen after a ""cabal install text"" on a fresh system, the problem would go away. Always building packages with the latest versions of their dependencies available isn't a solution, because dedukti could, for instance, depend on some specific version of bytestring yet text might happen to be built with another version on the Hackage server.

Could there be a way to at least detect when build failures are due to inconsistent versions in dependencies, which is a problem specific to the Hackage server installation and not the package itself?"	defect	closed	normal		hackageDB website		normal	fixed		mboes@…	unknown
