This isn't an fpm bug. It seems to be a problem specific to your computer.

fpm's install.sh uses curl to download files. curl is linked with libpsl—currently libpsl.5.dylib. libpsl is linked with libunistring—on your machine, libunistring.2.dylib, but that doesn't exist anymore; libunistring.5.dylib exists now. libpsl needs to be rebuilt now that libunistring has been updated.

libunistring was last updated (to 1.1_0) on October 22, 2022. It's presumably at that time that its dylib version changed to 5, therefore all ports that link with libunistring had their revisions increased (e.g. libpsl was updated from 0.21.1_0 to 0.21.1_1) the same day. That should have taken care of the problem, assuming that sometime after October 22, 2022 you've run:

sudo port selfupdate
sudo port upgrade outdated

If you've already done that and you already have libpsl @0.21.1_1 or later installed and active, then it was evidently built erroneously against the old libunistring. The solution would be to rebuild it against the current libunistring:

sudo port -n upgrade --force libpsl

Thank you! Indeed, I upgraded few ports on 10.4 but not all. I will go through updates, it should be good then.
