Direct Mail has the following external dependencies:

ZipKit.framework (https://bitbucket.org/kolpanic/zipkit/wiki/Home)
CSS.framework (https://github.com/jhammer/libcss-osx)

To get Direct Mail to build, you'll need to have the above dependencies downloaded and built (Release, 64-bit only) in the following location:

/Developer
  directmail
  zipkit
    build
      Release
        ZipKit.framework

You will probably need to change the release target on all of these frameworks/libraries to build x86_64 only

Direct Mail also depends on a custom build of libssl and libcrypto. You will find the openssl-xcode project inside the project root. Build libssl and libcrypto by following the instructions inside that project, then move the .a files into the project root.

When Direct Mail builds, it first builds the stationery webview plug-in. That plug-in will fail to build the first time through because it links against the Direct Mail binary (which hasn't been built yet). Once Direct Mail builds, then you can build again and the plug-in will build just fine (because now it can link against the DM binary)

You'll need to change ZipKit's Installation Directory to "@rpath"
