Many months ago, I tried to get a Debian 10 backport of net-snmp 5.9.
Unfortunately, there was zero interest.
Have you tried using the ldconfig tool, for recreating the dynamic
linker cache, printing it, etc? Based on what you have, that is what I
would look at next. (and LD_LIBRARY_PATH too)
Good luck,
John

attempting to compile on Debian 10 buster on i386 hardware have hit a
surprising error. Several shared libraries are not found/loading.

So I checked the library configuration...
# ls -l /etc/ld.so.conf.d
total 12
-rw-r--r-- 1 root root 36 Jun 25 2018 fakeroot-i386-linux-gnu.conf
-rw-r--r-- 1 root root 168 May 1 2019 i386-linux-gnu.conf
-rw-r--r-- 1 root root 44 Mar 20 2016 libc.conf
# cat /etc/ld.so.conf.d/libc.conf
# libc default configuration
/usr/local/lib
So why are the libraries not loading? Or being found by the snmpd
process?
