Nice!  I think that’s another interesting way to address the problem.

I guess the advantage is that you don’t need the ld.so patch.  The
downside is that PatchELF needs to be able to write longer NEEDED
strings in the dynamic section, which it may not always be successful at
(I think?).

Also, I wonder if the absolute file names in NEEDED interfere with uses
of $LD_LIBRARY_PATH (making it impossible to force use of another
libxyz.so than the one that would be found in RUNPATH.)

Thoughts?

Thanks for sharing!
