Questions[freebsd-ports](server)

I'm trying to find the full URL for downloading the Emby Server .txz package from FreeBSD repository, but I got no luck finding it on any search engines.

Farther I went was this FreeBSD repository list https://www.freebsd.org/cgi/ports.cgi?query=emby-server&stype=all but I could not find any URL in there.

My intention is to add and install this package directly through the URL, like this:

pkg add http://pkg.freebsd.org/FreeBSD:12:amd64/latest/All/emby-server1.1.1.txz

I'm using FreeBSD 12, amd64.

I'm playing with a FreeBSD installation inside a Virtualbox vm, and I want to keep the size of the image relatively small. How can I configure FreeBSD to clean distfiles after installing a port (using make, portupgrade, etc)?

Is there any way to remove build dependencies of the port after installing it?

Many ports use exotic tools for building and these tools are not used anymore when port is builded and installed.

Is there an easy way to check a ChangeLog of a FreeBSD port before you upgrade? For instance, I'd like to check what upgrades are mandatory before I do portmaster -ad. It would be nice to have something like portaudit, but for changelogs. The closest thing I know of is head -n 40 UPDATING.

I'm trying to build a port which depends on apache-ant.

I thought I could run make build-depends-list to see all dependencies required by this port:

# make build-depends-list
/usr/ports/devel/apache-ant
/usr/ports/java/jdk16
/usr/ports/math/gmp

But after installing everything, the port had a dependency list which was a mile long:

apache-ant-1.8.1 desktop-file-utils-0.15_2 gamin-0.1.10_4 gettext-0.18.1.1 gio-fam-backend-2.26.1 glib-2.26.1_1 gmp-5.0.1 inputproto-2.0 javavmwrapper-2.3.5 kbproto-1.0.4 libX11-1.3.3_1,1 libXau-1.0.5 libXdmcp-1.0.3 libXext-1.1.1,1 libXi-1.3,1 libXtst-1.1.0 libiconv-1.13.1_1 libpthread-stubs-0.3_3 libxcb-1.7 pcre-8.12 perl-5.10.1_3 pkg-config-0.25_1 python26-2.6.6 recordproto-1.14 unzip-6.0 xextproto-7.1.1 xproto

This dependency list is a rude surprise, and I would like to know about it before I commit to installing a port.

How can I see all dependencies, and all subdependencies for a port?
