The symbol _fprintf$LDBL128 doesn't exist prior to 10.4.

It sounds very much like you're compiling your plugin targeted for 10.4,
but running it under 10.2.8.

This won't work. For a host of reasons.

For your plugin to run under 10.2.8, you must do at least the following:
1. Use the 10.2.8 SDK.
2. Use the GCC compiler appropriate for 10.2.8 (gcc 3.3, IIRC).
3. Set your target OS version to 10.2.

You don't have to do item 1 above as long as you do any need runtime checks of API that came out after 10.2.8.

I suggest you set the SDK to the version of OS that you want to be able to use API from (say 10.4). As needed you can temporarily specify the max OS version to be 10.2 (MAC_OS_X_VERSION_MAX_ALLOWED) to cause the availability macros to complain about usage of post 10.2 API so that you can make sure you are doing the correct runtime checks.
