 # - libexpat creates a bsdxml library which is the same as expat
 # - archiving libraries (have their own ebuild)
 # - sendmail libraries (they are installed by sendmail)
 # - SNMP library and dependency (have their own ebuilds)
 # - libstand: static library, 32bits on amd64 used for boot0, we build it from
 # boot0 instead.
 #
 # The rest are libraries we already have somewhere else because
 # they are contribution.
 # Note: libtelnet is an internal lib used by telnet and telnetd programs
 # as it's not used in freebsd-lib package itself, it's pointless building
