Looks like xman traditional troff. mandoc(1) invocation is different.

A quick search shows the ports have more than one implementation.

$ rg -l bin/troff
textproc/heirloom-doctools/pkg-plist
devel/plan9port/pkg-plist
japanese/groff/pkg-plist
devel/9base/pkg-plist
textproc/groff/pkg-plist

Either USES=groff:run or https://github.com/openbsd/xenocara/commit/6de1c98f99cd
can fix it. Up to the port maintainer.

Likely. Manpages are often short and have standard layout, so navigation
is rarely necessary. A web browser can replace GUI.
