It's strange... On the one hand, I can see that the configure script was generated with ​a broken version of libtool (< 2.4.7) that predates its support for macOS 11 and later, with support for only macOS 11 patched in. Thus on macOS 11 and earlier, it will call for runtime handling of undefined symbols, and on macOS 12 and later, it won't. We have a standard patchfile we can apply to fix that. On the other hand, the port built successfully on our build system on all systems including macOS 12 and 13 suggesting that this software didn't make use of undefined symbols.
