if you really want your system to be used for building
slackpkg update slackpkg install \ rsync \ cyrus-sasl \ curl \ lz4 \ zstd \ xxHash \ nghttp2 \ brotli ldd /usr/bin/rsync | grep found ldd /usr/libexec/gnupg/gpgkeys_curl | grep found
grab the latest package
wget https://github.com/sbopkg/sbopkg/releases/download/0.38.3/sbopkg-0.38.3-noarch-1_wsr.tgz installpkg --terse sbopkg-0.38.3-noarch-1_wsr.tgz
sbopkg builds packages from source, so you might like to have a compiler and tools for building
sbopkg -r sbopkg -s colordiff sbopkg -i colordiff ls -lF /var/log/packages/colordiff*
in case you pushed /var/lib/sbopkg/ like a brute, you also need to import the GPG key over there
wget -q -O- https://slackbuilds.org/GPG-KEY | gpg --import -
#git clone https://github.com/sbopkg/sbopkg.git #wget https://github.com/sbopkg/sbopkg/releases/download/0.38.1/sbopkg-0.38.1-noarch-1_wsr.tgz #wget https://sbopkg.org/test/sbopkg-0.38.2-noarch-1_wsr.tgz #installpkg --terse sbopkg-0.38.1-noarch-1_wsr.tgz
and tune the config to point to master instead of latest release which does not exist there yet
# e.g. happened for 15.0 --> master
