 >Description:

Sorry if this is an inappropriate way to file bug reports, I am a 
non-OpenBSD developer compatibility-testing his fetchmail and bogofilter 
and leafnode packages on OpenBSD, too, but my main drivers are Fedora 
Linux and FreeBSD - and I haven't found something better how to report 
bugs in a port.

htmldoc-1.9.23 (installed as package through pkg_add; up to date as of 
2026-05-30, per pkg_add -uv)
- like its predecessor versions before - leak their build directory 
layout into the packages.

The result is a long chain of htmldoc error messages (many more 
repetitions of this):

ERR005: Unable to open font width file 
/usr/obj/ports/htmldoc-1.9.23/fake-amd64/usr/local/share/htmldoc/fonts/Times-Bold.afm!
ERR005: Unable to open font width file 
/usr/obj/ports/htmldoc-1.9.23/fake-amd64/usr/local/share/htmldoc/fonts/Helvetica-Bold.afm!
ERR005: Unable to open font width file 
/usr/obj/ports/htmldoc-1.9.23/fake-amd64/usr/local/share/htmldoc/fonts/Times-Roman.afm!


Prior versions of htmldoc in the past instead used to leak a literal(!) 
${DESTDIR} as path prefix.


 >How-To-Repeat:

1. Install git and htmldoc packages.

2. git clone https://gitlab.com/fetchmail/fetchmail.git

3. cd fetchmail

4. cp fetchmail-FAQ.html fetchmail-FAQ-print.html

5. /usr/local/bin/htmldoc --logoimage bighand.png --batch fetchmail-FAQ.book

See hundreds of ERR005 messages

 >Fix:

Please make sure that the package's build-time path, for instance, 
/usr/obj/ports/htmldoc-1.9.23/fake-amd64/, does not end up in the built 
binaries.

Workaround (system-specific, this works for amd64):

   doas mkdir -p /usr/obj/ports/htmldoc-1.9.23/
   doas ln -sfn / /usr/obj/ports/htmldoc-1.9.23/fake-`uname -m`
   doas chmod a+x /usr/obj
