Hey I have been able to compile and run Monodevelop on FreeBSD 10.2. The
source is from git and I use the gmake method to build. I am trying to load
the MonoDevelop workspace IN MonoDevelop to debug some issues, but when
loading I am getting the following error:

An unhandled exception has occured. Terminating MonoDevelop? True
System.TypeInitializationException: An exception was thrown by the type
initializer for LibGit2Sharp.Core.NativeMethods --->

The Workspace mostly loads (po triansaltions fail?) but when I try to
compile I get a very similar error. Incidently, I am trying to update the
FreeBSD port to 5.10 and something similar is what is failing there too.

I think I have tracked it down to this:
the LibGit2Sharp project contains a reference to a class file called
NativeDLLName.cs and in it is a string const:

namespace LibGit2Sharp.Core
    internal static class NativeDllName
        public const string Name = "git2-3d5286e";

This is what is loaded into NativeMethods.cs:

// ReSharper disable InconsistentNaming
namespace LibGit2Sharp.Core
    internal static class NativeMethods
        public const uint GIT_PATH_MAX = 4096;
        private const string libgit2 = NativeDllName.Name;
        private static readonly LibraryLifetimeObject lifetimeObject;
        private static int handlesCount;


        internal static extern GitErrorSafeHandle giterr_last();

        internal static extern void giterr_set_str(
            GitErrorCategory error_class,
            [MarshalAs(UnmanagedType.CustomMarshaler, MarshalCookie =
UniqueId.UniqueIdentifier, MarshalTypeRef = typeof(StrictUtf8Marshaler))]
string errorString);

        internal static extern void giterr_set_oom();

Can anyone tell me more about "git2-3d5286e"? Where will I find it if it
does exist?
