man(1) can't handle compressed included files.
Some ports will install with compressed manpages. man handles this by looking for the .gz version of a man source file. It is also common to include other files with the .so directive where commands or functions share a man page. Traditionally ports have had to handle this by either not compressing the manpages, or using the _MLINKS macro in the port makefile to create symlinks to the actual source file, rather than using .so versions. Notably, the current version of Xorg port breaks. See ports/113096 and ports/115845.
