We'll have to agree to disagree.  Works for me.

Good, then we agree moving things around after install is OK?

Unclear if your precondition matches the use case for libgpsdpacket.so.
I see many potential uses for it.

No reason?  Was I not clear that on Gentoo you do not know the
location at build/install time?  The whole point of dlopen() in
libc is to handle moving libs around, without touching rpath, etc.

Why avoid the way shared libs have worked for decades?
