I see your point. This probably causes the most trouble when
installing to a standard location like /usr/local or /usr; I was
rather assuming custom locations, which do not conflict with system

Solaris doesn't have the same mechanisms, there is no ld.so.conf or
ldconfig and 64-bit libraries are inside a symlinked subdir 64 (amd64
That would narrow the decision down to Solaris-only or not-at-all.
