I install the self compiled libs to /usr/local/lib64:

./configure --prefix=/usr/local --libdir=/usr/local/lib64

Then I set the path with ldconfig by creating two files 

/etc/ld.so.conf.d/simple-scan.conf and
/etc/ld.so.conf.d/xsane.conf

that contains the path /usr/local/lib64 and then I run ldconfig.

I also compile all backends. The rest is identical to your installation.
So I think the error I receive while scanning in 75 dpi flatbed lineart
is some problem with my local installation.
