# Slackware SlackBuild script
# ===========================
# By:         R. Andrew Bailey
# For:        ldns
# Descr:      The goal of ldns is to simplify DNS programming
# URL:        http://www.nlnetlabs.nl/projects/ldns/
# -----------------------------------------------------------------------------

# 20220308 bkw: Modified by SlackBuilds.org: fix build on 15.0:
# - parallel makes are broken, use -j1.
# - fix code that finds the /usr/share/vim/vimXX directory (it would
#   fail if there were more than one of them).
# - add python3 support, inspired by Dave Woodfall.
