Hey Carter, Thanks for getting back to me.
I've tried sticking a "network == 2.8.0.0" dependency into different combinations of the following files: - compiler/ghc.cabal.in - ghc/ghc-bin.cabal.in - utils/ghc-cabal/ghc-cabal.cabal - utils/ghc-pkg-ghc-pkg.cabal In addition, I've also tried adding a "-ilibraries/network" into utils/ghc-cabal/ghc.mk At the moment, there is evidently some progress, since it fails with: Configuring ghc-pkg-6.9... Configuring ghc-8.2.2... ghc-cabal: Encountered missing dependencies: network ==2.8.0.0 utils/ghc-pkg/ghc.mk:64: recipe for target 'utils/ghc-pkg/dist/ package-data.mk' failed make[1]: *** [utils/ghc-pkg/dist/package-data.mk] Error 1 make[1]: *** Waiting for unfinished jobs.... ghc-cabal: Encountered missing dependencies: network ==2.8.0.0 compiler/ghc.mk:587: recipe for target 'compiler/stage1/package-data.mk' failed make[1]: *** [compiler/stage1/package-data.mk] Error 1 Makefile:122: recipe for target 'all' failed make: *** [all] Error 2 However, from here I'm stuck. The network package that already exists on my system is also 2.8.0.0.
