Mac OSX, TGEA 1.8.1 Offline Docs Incomplete

#1 Okay, I found TGEA/Projects/Template, made a copy called it "MyAwesomeGame", and tried to compile it, "TGEA/Projects/MyAwesomeGame/buildFiles/Xcode/Template.xcodeproj"

414 errors, mostly dealing with these errors and errors similar to these.

error: 'MatInstance' has not been declared
error: 'GFXGLShaderConstBuffer' has not been declared
error: conflicting declaration 'typedef ptrdiff_t GLsizeiptr'
error: 'void (* glAlphaFunc)(GLenum, GLclampf)' redeclared as different kind of symbol

Judging that they are all complaining about declarations, I'm assuming that all the errors are somewhat related, anyone know whats causing it?

edit:
All of the errors are occurring in the Template part of compiling and not under the other 9 libraries it compiles before attempting to compile the application.

edit # 2:
Heres one of the errors,
In gfx/gl/gfxGLShader.h

class GFXGLShader : public GFXShader
{
[...]
protected:
friend class GFXGLShaderConstBuffer;
void setConstantsFromBuffer(GFXGLShaderConstBuffer* buffer); //This line is giving an error that GFXGLShaderConstBuffer doesn't exist
[...]
};
//This is right below the GFXGLShader class in the same header file.
class GFXGLShaderConstBuffer : public GFXShaderConstBuffer
{
public:
GFXGLShaderConstBuffer(GFXGLShader* shader, U32 bufSize);
[...]
private:
friend class GFXGLShader;
U8* mBuffer;
GFXGLShader* mShader;
};


These are the kinds of errors I'm running into while trying to compile. 414 of them.
Am I missing a link in the settings or something?

#2 I've decided to switch to another engine instead of attempting to work with this one anymore.
