bug in textproc/docbook-xsl ???

[Eugene M. Minkovskii]

I'm tring to use xsl with profiling, but got an error:

/usr/local/bin/xsltproc --profile --nonet my.xsl my.xml warning: failed to load external entity "/usr/local/share/xsl/docbook/profiling/profile-mode.xsl"
compilation error: file /usr/local/share/xsl/docbook/html/profile-chunk-code.xsl line 219 element include
xsl:include : unable to load /usr/local/share/xsl/docbook/profiling/profile-mode.xsl

to avoid this I do following:
$ tar -xjf /usr/ports/distfiles/docbook-xsl-1.69.1.tar.bz2
$ sudo cp -rv docbook-xsl-1.69.1/profiling /usr/local/share/xsl/docbook/
$ rm -rf docbook-xsl-1.69.1/

Why profiling does not install automatically?
