To build arts (3.5.12) from the stable repository, with autoconf, I applied a little sed substitution : $ cp -vp /usr/share/aclocal/libtool.m4 admin/libtool.m4.in && $ cp -vp /usr/share/libtool/config/ltmain.sh admin/ltmain.sh && $ make -f admin/Makefile.common && $ sed -e 's/qiomanager_p.h qiomanager_p.moc/qiomanager_p.h > qiomanager_p.moc/' -i qtmcop/Makefile.in and then ./configure ... && make && make install It may help.
