MarsSeed [1] filed a deletion request for ruby-pcap [2]: Package last updated 2015. Now the target resource that its source and upstream URL points to cannot be found (404).
There are several alternatives for the same use case as this was made for on RubyGems.org. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/ruby-pcap/
