Not the OP, but regarding DYLD_LIBRARY_PATH, I don't understand how to
make use of dylib's provided by macports in my own programs without
setting this flag. I've read in several places that, esp with macports,
this should not be necessary, but I don't know what the *right way* is.

Nothing of Apple's (such as
/Library/Developer/CommandLineTools/usr/libexec/git-core/git) should be
referencing anything of MacPorts's (such as /opt/local/lib/libiconv.2.dylib).
The only reason that might happen is if you set DYLD_LIBRARY_PATH. So don't set
that.
I can only fix this if I put /usr/lib in the front of DYLD_LIBRARY_PATH, but
this breaks tons of other command.
You should not need to set DYLD_LIBRARY_PATH at all. Why do you think you need
to?
So, I decided to install a git from macports, however, this attempt failed with
the following error:
fangq@jinwy:~/space/git/Project/autobuild/mcx$ sudo port install git
Warning: xcodebuild exists but failed to execute
Warning: Xcode does not appear to be installed; most ports will likely fail to
build.

for details.
Error: Follow https://guide.macports.org/#project.tickets to report a bug.

look at the main.log file, I found the error message attached at the end.
My macport version is 2.4.2, OS is Sierra, already ran port selfupdate.
I have an old version of xcode (7.3) in order to compile cuda code, but I don't
think it was the issue.
I agree that an old Xcode would not cause a patch failure, but note that macOS
Sierra requires Xcode 8 or 9.
can someone let me know how to fix this? alternative approaches, such as
portable git binaries are also welcome, thanks a lot!

The "Skipping" lines show us that this was not a clean attempt so no conclusions can be
reached from it. "sudo port clean git" and try again.
