SDL on FreeBSD, Revisited

I’ve installed libsdl_1.2.5 from ports, but it doesn’t seem to put a
corresponding libsdl.1.2.5.so file into my /usr/lib/ directory (or somesuch
location), like the 1.x version has done (I’ve seen it; it’s there).

How can I get that .so file built for version 1.2.5?

Thank you!!!
