I can confirm this on an 8.0-RELEASE/i386 machine. exp(3) lives in the 
math library, so those shared objects must be linked against it. Quick 
fix: when the build bombs out, edit 
/usr/ports/net-mgmt/net-snmp/work/net-snmp-5.4.2.1/agent/Makefile and 
modify this line:

LIBS            = $(USELIBS) -lelf -lssp_nonshared $(PERLLDOPTS_FOR_APPS)

...to be this:

LIBS            = $(USELIBS) -lelf -lssp_nonshared -lm 
$(PERLLDOPTS_FOR_APPS)

Also, edit 
/usr/ports/net-mgmt/net-snmp/work/net-snmp-5.4.2.1/apps/Makefile and 
modify this line:

TRAPDWITHAGENT  = $(USETRAPLIBS) -lelf -lssp_nonshared

...to be this:

TRAPDWITHAGENT  = $(USETRAPLIBS) -lelf -lssp_nonshared -lm


...then continue the build, which should now complete.
