Package apr-utils-devel should contains the apu*.m4 automake macro files in %{_datadir}/aclocal
Created attachment 311668 [details] Suggested SPEC file to fix the reported bug
Not applicable. These are internal files to build APU.
Unfortunately, I have to inform you, that the configure.ac file of subcommander will refer on it, so it neccessary to include this files to %{_datadir}/aclocal
You have fixed it in apr-util-1.3.2-8.fc10
