 Hi there!

 So I went to install FFmpeg and balked at the number of dependencies it
 wants to install.

 e.g.


 {{{
 % port -v rdeps ffmpeg-upstream
 }}}
 (then copy and paste that output into a file and run wc:)

 {{{
 % wc
 344     344   10972
 }}}

 Or if running:

 {{{
 % port -v install
 --->  Computing dependencies for
 ffmpeg...............................................................................................................................................................
 The following dependencies will be installed:
 }}}
 (omitting 158 ports listed)
 {{{
 Continue? [Y/n]:
 }}}

 Some of these, seem, *excessive* to understate it. kerberos5? rsync?

 So, I decided to instead:
 {{{
 % git clone https://git.ffmpeg.org/ffmpeg.git
 % cd ffmpeg
 % ./configure
 % make
 }}}

 Which seemed to function with 0 issues and produce a functional FFmpeg
 binary.

 Taking this one step further, I decided to create my own Portfile, and see
 if this was much different, and no surprise: it wasn't.

 Albeit, due to use of xz, the rdeps are still 8, but I am guessing even
 those could be whittled down if using a tar.gz instead of a .bz2?

 {{{
 % port -v rdeps
 The following ports are dependencies of ffmpeg @5.1.2_0:
   bin:xz:xz
     port:gettext
       port:diffutils-for-muniversal
       port:libiconv
         port:gperf
       port:libtextstyle
         port:ncurses
       port:gettext-runtime
       port:gettext-tools-libs
 }}}

 Now, I am guessing probably a lot of things in the existing Portfile are
 maybe useful for older builds of OS X than Ventura?

 Maybe there is some default variant stuff that is bringing along a lot of
 unnecessary cruft?

 Obviously, there's also the +nonfree variant which focuses on things which
 shouldn't be redistributed, but even without that the default dependencies
 seem to be an awful lot.

 Is there a way to turn that off some of this extra cruft and have a more
 minimal installation?

 I mean, well, obviously the test Portfile I created is one possible way;
 but I mean more generally?

 Thanks!
