But we have: laptop_93: {29} # pkg info -l xpdf | more xpdf-3.04_7: /usr/local/bin/xpdf ... /usr/local/share/xpdf/man/man1/pdfdetach.1.gz /usr/local/share/xpdf/man/man1/pdffonts.1.gz /usr/local/share/xpdf/man/man1/pdfimages.1.gz /usr/local/share/xpdf/man/man1/pdfinfo.1.gz /usr/local/share/xpdf/man/man1/pdftohtml.1.gz /usr/local/share/xpdf/man/man1/pdftopng.1.gz /usr/local/share/xpdf/man/man1/pdftoppm.1.gz /usr/local/share/xpdf/man/man1/pdftops.1.gz /usr/local/share/xpdf/man/man1/pdftotext.1.gz /usr/local/share/xpdf/man/man1/xpdf.1.gz /usr/local/share/xpdf/man/man5/xpdfrc.5.gz The man pages have been put in /usr/local/share/xpdf but not in /usr/local/man. I note that other packages have put their man pages in /usr/local/man.
This is intentional as it resolves a conflict with poppler. If the man pages are relocated back to $LOCALBASE/man, ports/packages requiring either cannot be installed together. You can always use MANPATH.
