ldd doesn't work with 64bit .so library on AIX

I generated my shared library in 64bit on AIX, but when I ran ldd, it says:

Could not load program libmylib.so:
Could not load module libmylib.so.
The module has an invalid magic number.

Anyone knows how to list library dependencies with 64bit shared library on AIX?

If you suggest nm or dump, could you please give the detail command line example?

Thanks a lot,
