3 questions:

1. What about deprecated methods?
'NSAddImage' is deprecated (declared at /Developer/SDKs/MacOSX10.6.sdk/usr/include/mach-o/dyld.h:230)
'NSLookupSymbolInImage' is deprecated (declared at /Developer/SDKs/MacOSX10.6.sdk/usr/include/mach-o/dyld.h:182)
'NSAddressOfSymbol' is deprecated (declared at

2. I couldn't compile when the _DEBUG flag is on (ERRORS), until I pasted the code from the previous link. Is that right?

3. Your contact link doesn't work: http://tightenapp.com/Contact.html

Those methods are deprecated, but they are used in the Darwin source code, which is where I went for the recommended method of symbol loading.

Regarding compile-time errors, depending on which compiler you have selected (GCC, GCC LLVM, LLVM, etc) you may need to modify the _DEBUG code. I'll have a fix for that in a future release.
