That seems to be the correct version for jessie.

Apparently, this has been reported already.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=794803

It looks like this is not due to the current version of libhpmud trying
to use old libnetsnmp15, but due to old hpmud-related files being left
around.

I found an Ubuntu bug report from mid-2014:
https://bugs.launchpad.net/ubuntu/+source/hplip/+bug/1245010
It looks like you can run
locate hpmudext.so
locate libhpmud.so
and after that, for each entry <file> resulting from these commands,
ldd <file> | grep netsnmp
If any snmp15 lines show up, then <file> might be the culprit, so you
can try removing <file>.
(If the snmp15 error goes away, but you still have problems, you might
try reinstalling hplip and libhpmud0 again.)
