When I check the attributes available to the module pcap, I expect to see something like

'DLT_AIRONET_HEADER', 'DLT_APPLE_IP_OVER_IEEE1394', 'DLT_ARCNET', 'DLT_ARCNET_LINUX', 'DLT_ATM_CLIP', 'DLT_ATM_RFC1483', 'DLT_AURORA', 'DLT_AX25', 'DLT_CHAOS', 'DLT_CISCO_IOS', 'DLT_C_HDLC', 'DLT_DOCSIS', 'DLT_ECONET', 'DLT_EN10MB', 'DLT_EN3MB', 'DLT_ENC', 'DLT_FDDI', 'DLT_FRELAY', 'DLT_IEEE802', 'DLT_IEEE802_11', 'DLT_IEEE802_11_RADIO', 'DLT_IEEE802_11_RADIO_AVS', 'DLT_IPFILTER', 'DLT_IP_OVER_FC', 'DLT_JUNIPER_ATM1', 'DLT_JUNIPER_ATM2', 'DLT_JUNIPER_ES', 'DLT_JUNIPER_GGSN', 'DLT_JUNIPER_MFR', 'DLT_JUNIPER_MLFR', 'DLT_JUNIPER_MLPPP', 'DLT_JUNIPER_MONITOR', 'DLT_JUNIPER_SERVICES', 'DLT_LINUX_IRDA', 'DLT_LINUX_SLL', 'DLT_LOOP', 'DLT_LTALK', 'DLT_NULL', 'DLT_PFLOG', 'DLT_PPP', 'DLT_PPP_BSDOS', 'DLT_PPP_ETHER', 'DLT_PPP_SERIAL', 'DLT_PRISM_HEADER', 'DLT_PRONET', 'DLT_RAW', 'DLT_RIO', 'DLT_SLIP', 'DLT_SLIP_BSDOS', 'DLT_SUNATM', 'DLT_SYMANTEC_FIREWALL', 'DLT_TZSP', 'builtins', 'doc', 'file', 'name', '_newclass', '_object', '_pcap', '_swig_getattr', '_swig_setattr', 'aton', 'dltname', 'dltvalue', 'findalldevs', 'lookupdev', 'lookupnet', 'ntoa', 'pcapObject', 'pcapObjectPtr']

With note on pcapObject. However, all I get when running dir(pcap) is

['DLT_ARCNET', 'DLT_AX25', 'DLT_CHAOS', 'DLT_EN10MB', 'DLT_EN3MB', 'DLT_FDDI', 'DLT_IEEE802', 'DLT_LINUX_SLL', 'DLT_LOOP', 'DLT_NULL', 'DLT_PFLOG', 'DLT_PFSYNC', 'DLT_PPP', 'DLT_PRONET', 'DLT_RAW', 'DLT_SLIP', 'author', 'builtins', 'copyright', 'doc', 'file', 'license', 'name', 'url', 'version', 'bpf', 'dltoff', 'ex_name', 'lookupdev', 'pcap', 'sys']

Noting the lack of pcapObject. Why is this? What could cause this?
