when md2man cannot create manpages (configure check tells "checking if md2man can create manpages... no") and rsync is build with "--with-rrsync" configure switch , make bails out with

i can reproduce this on linux, whereas i came across this when adding "--with-rrsync" to rsync.rb in homebrew project. automated build/ci failed after that. it seems macos einvironment does not have proper python dependencies for that , though brew formulae are installed.

% ./md-convert --test rsync-ssl.1.md
Failed to find cmarkgfm or commonmark for python3.

% brew search cmark
==> Formulae
cmark ✔                                      cmark-gfm ✔

# find . -name "*.1.md"
./rsync.1.md
./support/rrsync.1.md
./rsync-ssl.1.md

# find . -name "*.1"
./rrsync.1
./rsync-ssl.1
./rsync.1

there is a patch for quite a while in the debian package to adress this, but it looks weird/wrong to me

https://sources.debian.org/patches/rsync/3.4.1+ds1-8~exp1/fix_rrsync_man_generation.patch/

any reason why rsync-ssl and ./rsync-ssl.1.md is in ./ and rrsync and rrsync.1.md are in ./support - and why rrsync has it's own configure switch whereas rsync-ssl hasn't ?

easiest fix would be to move rrsync* out of support to be equally handled like rsync-ssl - both helper tools are more or less equally popular/important. so i'm wondering why they are stored at differnt levels in source.
