Rubygem passenger flavors in FreeBSD

The latest bit of code to adopt the trendy new “flavors” model is passenger. As “flavors” aren’t supported in Portmaster, this means the transition results in errors like:

/bin/rmdir /var/ports/usr/ports/www/rubygem-passenger/work-apache/stage/usr/local/lib/ruby/gems/2.4/extensions 2> /dev/null || true
( cd /var/ports/usr/ports/www/rubygem-passenger/work-apache/passenger-5.1.12 &&  /bin/sh -c '(/usr/bin/find -Ed $1 $3 | /usr/bin/cpio -dumpl $2 >/dev/null 2>&1) &&  /usr/bin/find -Ed $1 $3 \(   -type d -exec /bin/sh -c '\''cd '\''$2'\'' && chmod 755 "$@"'\'' . {} +  -o -type f -exec /bin/sh -c '\''cd '\''$2'\'' && chmod 0644 "$@"'\'' . {} + \)' COPYTREE_SHARE buildout /var/ports/usr/ports/www/rubygem-passenger/work-apache/stage/usr/local/lib/ruby/gems/2.4/gems/passenger-5.1.12 )
find: buildout: No such file or directory
find: buildout: No such file or directory

You can make with flavors manually or (assuming your current version is 5.1.12, adjust as needed):

# portmaster -o www/rubygem-passenger rubygem-passenger-5.1.12
