# Here we disable and remove source which we don't need or want
# In order:
# - ncurses stuff
# - archiving libraries (have their own ebuild)
# - sendmail libraries (they are installed by sendmail)
# - SNMP library and dependency (have their own ebuilds)
#
# 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
# it here.
