>Description:
While trying to build mongodb-2.0.7 from pkgsrc-wip I get following error:

Which seems like a problem in NetBSD includes

 Are you sure your header files are from the beta2?
 In my version, both declarations have C linkage (/usr/include/pcap/bpf.h uses
 __BEGIN_DECLS, /usr/include/pcap.h has it spelled out as extern "C")

 That's system I've just installed using
 http://mirror.corbina.net/pub/NetBSD/iso/6.0_BETA2/NetBSD-6.0_BETA2-amd64.isoimage,
 so I think headers should be from BETA2. Is there any way to check
 their version?

 Can you please verify that the two function declarations the compiler mentions
 are inside __BEGIN_DECLS/__END_DECLS (in bpf.h) or explicitly wrapped in

 #ifdef __cplusplus
 extern "C" {
 #endif

 and a coresponding } (in pcap.h)?

 pcap.h is cleverly missing CVS ID strings, so not all that easily.

 Try this:

 % find /usr/include/ -name '*pcap*.h' -type f -print | xargs md5

 I believe it should give you:

 MD5 (/usr/include/pcap/pcap.h) = def462156a0719cdc243e6c3ac26ff60
