I think I got it. It turns out that it's our gdb in base that can't read the debug info. lldb and gdb from ports do it just fine.

I also thought about recompiling library dependecies, but something didn't fit in, because not only the libraries calls were not there, but the calls from the port itself as well.

Thanks anyway!
