[ALUG] Mandrake / automake version

Hi. I'm trying to build ardour from CVS on Mandrake 10 community. When I run autogen.sh I get a message telling me I need automake >=1.5 (Mandrake uses 1.4 as standard). I tried changing the symlinks for aclocal and automake in /etc/alternatives/ to the 1.7 versions and running aclocal but I got a message saying aclocal: configure.ac: 4: macro `AM_BUILD_ENVIRONMENT' not found in library Can anyone explain what I need to do to use a later version of automake? Thanks for any help.
