Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64.

This is unfortunate. The docbook toolchain seems to have always
generated a lot of spew from fop, which to the SCons project has seemed
"out of our control". Now it seems something has changed so where the
java used to throw SEVERE it is now throwing ERROR, thus failing the
build - which really has nothing to do with the operation of SCons,
which is just a Python package, after all. This is a failure to
generate the pdf versions of the docs, which are unused by the deb
package, afaict.

Relevant part (hopefully):

The latest upstream release (4.7.0) tried to provide a way to avoid
doing the pdf and Sphinx builds, but it turns out it doesn't do that in
a place that the Debian packaging uses anyway. Will make a note to
revisit that on our end.

Didn't realize the deb directly used the build files in doc/man and
doc/user. The quickest way to patch around this would seem to be to
comment out or remove the check in

doc/man/SConstruct
doc/user/SConstrcut

which checks for the presence of the 'fop' or 'xep' commands, so that
'has_pdf' remains false, and the pdf build thus isn't attempted at all.
I assume you don't need the pdf files, just the scons.1 etc. files?
that's all I see copied in https://salsa.debian.org/debian/scons/-/blob/master/debian/rules?ref_type=heads
