[Nix-dev] git svn and how to install it please?

[Tony White]

Hi,
I'd like to use git svn which is a perl module, it's specified in
/etc/nixos/nixpkgs/pkgs/applications/version-management/git-and-tools/default.nix,
however I can't see how to install it.
I've got :

	  environment = {
	  extraPackages = [
	  pkgs.git
	  ];  };

In configuration.nix and git is there and I can use it from a konsole,
however if I try to use git svn in a konsole, it complains about it
the missing perl module.

Can't locate SVN/Core.pm in @INC

I can see :

svnSupport = getConfig ["git" "svnSupport"] false; # for git-svn support

in /etc/nixos/nixpkgs/pkgs/applications/version-management/git-and-tools
but how do I specify to install it or have I found a problem?

My first thought was that it was something like :

	  pkgs.git.svnSupport

That's obviously wrong though.

Thanks,
Tony
