Example rtpextract does not compile

tnteverett has asked for the wisdom of the Perl Monks concerning the following question:

http://cpansearch.perl.org/src/SULLR/Net-Inspect-0.303/tools/rtpxtract.pl

I am not able to resolve a Line 62 Error:

rtpextract.pl

Undefined subroutine &main::pcap_open_offline called at ~/bin/rtpextract.pl line 62.

Anyone know what the problem is here?

Tip #11 from the Basic debugging checklist: Is your installed version the latest version? The first thing you should try is to upgrade to 0.304.	[reply]

Also, try upgrading Net::Pcap too, the methods with `pcap_` prefix were added in 0.15.	[reply] [d/l]

Everything was upgraded with the latest. What I found was that the line 6 "use Net::Pcap qw(:functions);" had to be changed to "use Net::Pcap;". Once this was done the example compiled. I have never used this feature before and do not yet understand why it failed.	[reply]
