Why does opam 1.1.1 require Mavericks?

[FranklinChen]

I have an old Mac (from 2008) running Mac OS X 10.7.5 (the latest version available for the Mac). The latest opam will not install:

$ brew upgrade opam
==> Upgrading 1 outdated package, with result:
opam 1.1.1
==> Upgrading opam
gringo: OS X Mavericks or newer is required.
Error: An unsatisfied requirement failed this build.

Looks like this isn't actually opam, but a couple levels down the dependency tree - gringo, a dependency of aspcud (an optional dependency of opam).

Seems like gringo actually requires C++11, which is something that needs to get fixed up - it's not a 10.9 dependency.

Can we please change it, then? :)

[examachine]

oh there it is on the opam site:

brew install opam --without-aspcud

Should we make this switch only available 10.8 and up?

Ping @MerelyAPseudonym.

[adamv]

@Homebrew/owners any objections to making this dependency conditional on OS X version?

[MikeMcQuaid]

@adamv Seems fine.

It put in a pull request, but since gringo is marked as needing c++11 now, is this issue moot? @mistydemeo
