Many ports which are essential for the FreeBSD system (like cmake for example) require the existence of Curl and try to download it and install it from ports. Directadmin is duplicating the installation (overrides the port installation). It's not a big problem, but my opinion is that you can safely leave the management of Curl to be from ports.
It's the same with nghttp2. Directadmin overrides the ports installation.
