lain already answered your question with the best way to get the version string,
but to add some recent history:
A few months back the FreeBSD team switched packages from using .txz extensions
to .pkg, and used tildes (~) instead of dashes (-), which broke `pkg clean' or
`pkg autoclean', I forget which. During that time I wrote an awk script to
clear my various pkg repos using the following pattern matches:
{ sub(/\/.+\//, "") } # strip pathname from filename
/[-~][[:alnum:]]{10}.(txz|pkg)$/ { # binaries end in 10-alnum chars
ext = substr($0, match($0, /.(pkg|txz)$/)) # bin file extension
ver = substr($0, 0, match($0, /[-~][^-~]+$/) -1) # package version name
pkg = substr(ver, 0, match(ver, /-[^-]+$/) -1) # package base name
