Bug#906412: svn-buildpackage: FTBFS in buster/sid (po4a-build: Command not found)

[Santiago Vila <sanvila@debian.org>]

Package: src:svn-buildpackage
Version: 0.8.6
Severity: serious
Tags: ftbfs

Dear maintainer:

I tried to build this package in buster but it failed:

--------------------------------------------------------------------------------
[...]
 debian/rules build-indep
dh build-indep
dh: Compatibility levels before 9 are deprecated (level 7 in use)
   dh_update_autotools_config -i
   dh_auto_configure -i
dh_auto_configure: Compatibility levels before 9 are deprecated (level 7 in use)
   dh_auto_build -i
dh_auto_build: Compatibility levels before 9 are deprecated (level 7 in use)
	make -j1
make[1]: Entering directory '/<<PKGBUILDDIR>>'
po4a-build 
make[1]: po4a-build: Command not found
make[1]: *** [Makefile:10: docbuild] Error 127
make[1]: Leaving directory '/<<PKGBUILDDIR>>'
dh_auto_build: make -j1 returned exit code 2
make: *** [debian/rules:4: build-indep] Error 2
dpkg-buildpackage: error: debian/rules build-indep subprocess returned exit status 2
--------------------------------------------------------------------------------

The build was made with "dpkg-buildpackage -A" in my autobuilder.
Most probably, it also fails here in reproducible builds:

https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/svn-buildpackage.html

where you can get a full build log if you need it.

If this is really a bug in one of the build-depends, please use reassign and affects,
so that this is still visible in the BTS web page for this package.

Thanks.
