The problem seems to be the dlopen "/usr/lib64/libgnucash-guile.so", that's the old 4.5 library installed by the distribution. Copying the new generated library build/lib64/libgnucash-guile.so to /usr/lib64 fixes the issue, but that's a pretty ugly hack.

You don't need to replace the old libraries, just remove them. Then Guile won't be able to find them and will fall back to looking where it's told to, in the build directory. Kinda like that (probably apocryphal) Churchill quote about Americans always doing the right thing after they'd exhausted all of the alternatives. Make/ninja uninstall is easiest but doesn't always work if there are filename changes and the builddir or sourcedir are reused. If it fails it's usually enough to remove libgnc* from the install library folder; sometimes you also need to remove the installed *.scm and *.go files from their respective directories in libdir/guile/version/ccache and sharedir/guile.
