25	vector shouldn't build-depend on ghc	anonymous		"a package should build-depend on ghc only if it's using the ghc-api library, which comes in a package called ""ghc"".
vector currently doesn't use that library but it's still needlessly tied to ghc via the dependencies stored by ghc-pkg, when installed, this makes it very vulnerable to a serie of issues related to the diamond dependency problem and eager shadowing based on ABI hash.

it should use the following instead:
{{{
if impl(ghc < 6.9)
    buildable: False
}}}"	defect	closed	blocker	0.7.0.1		fixed
