If you install over an older version of ghc, you will have a leftover
package cache from the old version which will cause package lookups to
fail. Someone else just tripped over this in IRC after installing a new ghc
over an old one; the Arch 8.2.2 upgrade from 8.2.1 also seems to be
susceptible to this. Rebuilding the package cache (ghc-pkg recache
--global; with sudo if installed as root) will fix this.

I tried to build the release from this script [1] which works straightfully for GHC 8.2.2 on debian jessie. 1) There's a minor glitch showing: GHC_VERSION = 8.4.1 but the version of the file in the download area is 8.4.0.20171214
2) GHC and cabal library installed successfully whereas cabal-install failed with this error:
Linking Setup ... Configuring HTTP-4000.3.7... Setup: Encountered missing dependencies: base >=4.3.0.0 && <4.11
Error during cabal-install bootstrap: Configuring the HTTP package failed.
Any hint ?
