Peter Simons 40bb2781ee cabal: add "-hidir $TMPDIR" parameter to ghc call that compiles Setup.hs ... Packages that don't have a Setup.hs file get to use a default version that lives in the Nix store. By default ghc tries to put the Setup.o and Setup.hi files in the same directory as the source file, which isn't writable. This leads to build errors [1]. Thus, we re-direct those paths to a build-local writable location: $TMPDIR. Arguably, we could also use "." or copy the /nix/store/deadbeef-Setup.hs file into the local source directory before compiling, which would work fine, too.
