Trying to build using ghc 7.8 on debian linux results in errors:

I also found it a little strange that the version number cloned from github is one less than pulled from hackage. But the hackage version seems to have similar issues (not building).
Please let me know if I can provide other info.
what's the output of cabal configure -v2? (I'm especially interested in the build-dep selection and the cabal version used)
I suspect this is not a problem with the HTTP package but rather a problem with the cabal version you use, which is too old for GHC 7.8
FYI HTTP does work for me in GHC 7.8, and I routinely test with all the released GHC versions that the "build-tools" lists as being supported.
Apologies for the github version falling behind, I forgot to push the most recent release. Now fixed.
Assuming this is ok now - please reopen with repro steps if not.
