Normally, the pyzmq package in Sage should link against the zeromq
built for Sage, so you might want to make sure that libzmq really
built and installed correctly, and that you don't have any funny
compiler flags set. Also try manually unpacking the pyzmq sources and
compiling the vers.c module as seen in the logs:
gcc -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall
-Wno-unused -fPIC -I/opt/modules/sagemath/8.1/include -Izmq/utils
-Izmq/backend/cython -Izmq/devices -c
build/temp.linux-x86_64-2.7/scratch/vers.c -o
build/temp.linux-x86_64-2.7/scratch/vers.o
gcc build/temp.linux-x86_64-2.7/scratch/vers.o
-L/opt/modules/sagemath/8.1/lib -Wl,-R/opt/modules/sagemath/8.1/lib
-lzmq -lrt -o build/temp.linux-x86_64-2.7/scratch/vers
