Comment (by mouse07410):

 OK, a (more) complete reproducer, assuming you're in
 {{{OpenSC/doc/tools/}}} directory, aka, you cloned
 [https://github.com/OpenSC/Opensc.git]:

 {{{
 $ pwd
 /Users/ur20980/src/OpenSC/doc/tools
 $ cp ../man.xsl .
 $
 $ sed -e 's|@pkgdatadir[@]|/Library/OpenSC/share/opensc|g' < dtrust-
 tool.1.xml > dtrust-tool.1.ed.xml
 $ less dtrust-tool.1.ed.xml
 $ xsltproc --path "/opt/local/share/xsl/docbook-xsl-nons/manpages/" -o
 dtrust-tool.1 man.xsl < dtrust-tool.1.ed.xml
 I/O error : failed to load "docbook.xsl": No such file or directory
 compilation error: file man.xsl line 3 element import
 xsl:import : unable to load docbook.xsl
 $
 }}}
