Hi I'm trying to compile the heartbeat 2.0.7 srpm from the .dev.centos site on rhel 4 es. But I'm getting the following error: checking for ucd-snmp/snmp.h... no checking net-snmp/net-snmp-config.h usability... yes checking net-snmp/net-snmp-config.h presence... yes checking for net-snmp/net-snmp-config.h... yes checking for net-snmp-config... /usr/bin/net-snmp-config checking for special snmp libraries... -L/usr/lib -lnetsnmp -lcrypto -lelf -lm checking snmp libraries: -lxml2 -lc -luuid -lrt -ldl -L/usr/lib -lnetsnmp -lcrypto -lelf -lm... ok checking snmp libraries: -lxml2 -lc -luuid -lrt -ldl -L/usr/lib -lnetsnmpagent -lnetsnmpmibs -lnetsnmphelpers -lnetsnmp -lsensors -ldl -lrpm -lrpmio -lpopt -lbz2 -lz -lcrypto -lelf -lm -L/usr/lib/lib -lwrap... configure: error: cannot link with requested libraries (-lxml2 -lc -luuid -lrt -ldl -L/usr/lib -lnetsnmpagent -lnetsnmpmibs -lnetsnmphelpers -lnetsnmp -lsensors -ldl -lrpm -lrpmio -lpopt -lbz2 -lz -lcrypto -lelf -lm -L/usr/lib/lib -lwrap).
