Going with plain text / pure ASCII, no HTML, no "smart
formatting", is the best thing to do. However, "clever"
tools which know better than you will change your message
and destroy the formatting you did, or destroy the formatting
of the incoming messages so it's "more fun" for you to read.
If you can, switch off all that "cleverness" for this
mailing list - it just results in misleading and wrong
content in the list and its archives.

By the way, you can check the mailing list archives to see
how the messages are supposed to look like (form-wise). ;-)

That is already the problem where you see the interference
with the ports system: Sources managed, build and installed
with ports tools have to meet certain specifications. Sources
obtained from Github, being processed outside of the scope
of the ports toolchain, do not integrate well.

See "man 7 ports" for details.

Port maintainers who develop software for FreeBSD tend so
work with a local ports tree, and often use poudriere as
a build environment. FreeBSD uses SVN (Subversion) as a
revision control system for the ports tree itself. Port
maintainers can use git / Github independently, but those
are not part of the FreeBSD ports "ecosystem".

I mention this as using portsnap will not always give you
the most current version of the ports tree, that's why
using svn checkout is preferred in such a case.

This is something that the port's Makefile can communicate
to the ./configure step. The port's options framework should
be used to allow the user to define options as you mentioned,
they usually aren't to be set manually:

port options	--->	./configure options	---> 	build
[ ] FOO			--option-FOO=1
[ ] BAR			--option-bar=enable
[ ] BAZ			--with-baz

(Again, "cleverness" changed "--" to "– " which is wrong.)

A first step is to determine if if you find some ./configure
or autotools settings in that port which do not have a
suitable option (selectable in "make config" or using a
Makefile.local additional file).

There are more people on this list who are deeper involved in
port management and development, they can probably offer a
much more detailed and accurate answer. However, what you
could try, is to use the ports collection as intended: Get
the latest version of the tree, diff that against the tree
obtained with git (just in case it's not current), and check
or uncheck the options in "make config"; if you find options
missing, e. g., there is some ./configure setting like
--option-blah=xyz, but the port does not have a corresponding
port option WITH_BLAH, you could add that experimentally, and
if it works as intended, offer a patch to help the further
development of the port in question. This eliminates the
problem that there is an option the ports framework is not
aware of, and therefore cannot handle it properly.

The core idea is to move the sources for use into the correct
place within the ports collection, both as "the files" and
"the concepts" (options).

The sources used to build within the ports tree belong into
/usr/ports/<category>/<name>/<work>. Without further knowledge
about what you're trying to achieve, I cannot recommand exact
commands to be entered. But the general path should be clear
now.

Especially sctions 4, 5.13, 6.6 and therefore 17.4 seem to be
valuable here, as well as example 5.10 (related to GitHub).
