I would like to install and use rrdtool but which need to be configured GRAPH support. For that reason I check the following page (https://docs.opnsense.org/manual/software_included.html#the-ports-tree) to use the existing ports and build it by my own.
What I've done so far:
cd /usr/ports/databases/rrdtool
make config
make reinstall
But for some reason after another install via the web interface all dependencies got removed. This result in a broken rrdtool because of missing dependencies. A pkg upgrade started a reinstall of the version from opnsense.
What would be the easiest and correct way to build / modify an existing package and install it with all dependencies?
Thanks for your support.
