This is frustrating.   First of all... the error that it can't find
'libssl.so.2' is because they are using a different (probably newer)
version of OpenSSL from when you linked it last.  Re-compiling it would
fix that problem -- which brings us to the next problem...

All of the errors below this point are due to this error.   The openssl
include file called kssl.h requires another include file called krb5.h
which it can't find on your system.

This is quite frustrating because we do not directly require kerberos.
Rather, the openssl header file requires it.  That's supposed to be
transparent to TN5250 and other apps.  You don't have to explcitly
code for it in FreeBSD.  Or RedHat 6.  Or RedHat 7.  Or RedHat 8...
why change that in RedHat 9?

(Okay, enough complaining for now...)

I'm not sure what the "proper" fix for this is, but as a quick hack
to get you up and running...

1) edit the file called /path/to/tn5250/src/Makefile.in
2) find the line that starts with "INCLUDES".  On mine it looks like this:
     INCLUDES = -DSYSCONFDIR=\"$(sysconfdir)\"
3) change it to include the directory where the krb5.h file is, like this:
     INCLUDES = -I/usr/kerberos/include -DSYSCONFDIR=\"$(sysconfdir)\"
4) ./configure
5) make
6) shell to root (if not already)
7) make install

I'll have to do some research to find the "correct" fix.  But for now,
that should get you going.  Good luck!
