Mavericks cannot bootstrap due to missing curl dependencies

[jwiegley]

Using a virgin Mavericks machine, nix-env -i curl fails to configure with the following error:

checking run-time libs availability... failed
configure: error: one or more libs available at link-time are not available run-time. Libs used at link-time: -lssh2 -lssh2 -lssl -lcrypto -lldap -lz
builder for ‘/nix/store/cy8ybjfj0xd8jbpcj9yqi3lk4knvywzk-curl-7.39.0.drv’ failed with exit code 1

The workaround to get things started is to change all-packages.nix:

--- a/pkgs/top-level/all-packages.nix
+++ b/pkgs/top-level/all-packages.nix

   curl = callPackage ../tools/networking/curl rec {
     fetchurl = fetchurlBoot;
-    zlibSupport = true;
+    zlibSupport = false;
     sslSupport = zlibSupport;
     scpSupport = zlibSupport && !stdenv.isSunOS && !stdenv.isCygwin;
   };

Once all of the necessary libraries are built by Nix this isn't needed anymore, so I think the right solution is simply to increase the dependency set for curl when zlibSupport is true.

Or maybe not zlibSupport, but one of those *Support flags is missing a needed dependency.

It seems all the libraries are present. I will keep digging.

The underlying error is:

Here is a fix that works for me:

This is not the right fix; see #5608.
