(and from Hydra). It is still possible to install any of those packages by
referring to them by attribute:
| $ nix-env -iA haskellPackages_ghc6104.hopenssl --dry-run
| (dry run; not doing anything)
| installing `haskell-hopenssl-ghc6.10.4-1.6.1'
| these paths will be fetched (50.61 MiB download, 450.34 MiB unpacked):
| /nix/store/rjsgga1fdqin47n2rkfn9l7v9ncsfh9l-haskell-hopenssl-ghc6.10.4-1.6.1
| /nix/store/y567qhqbjxbkldg3kq2clzn52a56cmdn-haskell-mtl-ghc6.10.4-1.1.0.2
| /nix/store/zbn24z1443fbrx6ch1nn2vnss9bdw1g0-ghc-6.10.4
It's no longer possible to install those by name anymore, though:
| $ nix-env -i haskell-hopenssl-ghc6.10.4
| error: selector `haskell-hopenssl-ghc6.10.4' matches no derivations
That style works only for active GHC versions 7.4.2 and 7.6.2:
| $ nix-env -qaP \* | grep haskell-hopenssl
| haskellPackages.hopenssl haskell-hopenssl-ghc7.4.2-1.6.1
| haskellPackages_ghc742_no_profiling.hopenssl haskell-hopenssl-ghc7.4.2-1.6.1
| haskellPackages_ghc742_profiling.hopenssl haskell-hopenssl-ghc7.4.2-1.6.1-profiling
| haskellPackages_ghc762.hopenssl haskell-hopenssl-ghc7.6.2-1.6.1
These changes intend to ease the load on Hydra. If you desperately need
pre-build binaries of any of those old versions, please post a short note
on the nix-dev mailing list.
