I've searched quite a bit, and the closest thing I found to this same question was this (also unanswered) question:
Symbol not found: _libintl_gettext
I'm attempting to make a thin c++ wrapper for libpuzzle.

Ok, so this error makes sense to me, clearly it can't load a dynamic library.
At first I thought I had to adjust my binding.gyp to include the linker settings, so I tried several different configurations. At the moment this is what it looks like:
{
"targets": [
{
"target_name": "puzzle",
"sources": [ "puzzle.cc" ],
"link_settings": {
"libraries": [
"/opt/local/lib/libgd.dylib",
"/opt/local/lib/libpuzzle.dylib"
],
}
}
]
}
I have the libs here:
$ ll /opt/local/lib/libpuzzle.*
-rwxr-xr-x 1 root admin 19K Jan 30 21:24 /opt/local/lib/libpuzzle.1.dylib

-rwxr-xr-x 1 root admin 1.2K Sep 2 23:59 /opt/local/lib/libgd.la
I just can't figure out how to get dyld to see them. I have tried adjusting DYLD_FRAMEWORK_PATH and DYLD_FALLBACK_LIBRARY_PATH to no avail.

The symbol that dyld is complaining about is __Z19puzzle_init_contextP14PuzzleContext_. In its unmangled form, it is puzzle_init_context(PuzzleContext_*). The mangling indicates that it was considered by the compiler to be a C++ symbol. However, libpuzzle appears to export a pure C interface. This means that the symbol it should be looking for is _puzzle_init_context. You can fix this by wrapping the #include <puzzle.h> in an extern "C" { … } block to inform the compiler that the contents of the header should be treated as C code, so it will handle the symbol names by the appropriate rules.
This sort of error is typically detected by the static linker rather than at runtime by the dynamic linker. The Expected in: dynamic lookup portion of your error message indicates that puzzle.node was linked with -undefined dynamic_lookup. This tells the static linker not to emit any errors for undefined symbols, but instead to have the dynamic linker attempt to resolve the symbols at runtime. This is rarely the behavior you want.
