[squid-users] Building from bzr repo

1) When I do an initial checkout OR bzr update, I'm getting:

# bzr update
Doing on-the-fly conversion from RepositoryFormatKnitPack1() to RepositoryFormatKnitPack6().
               
This may take some time. Upgrade the repositories to
the same format for better performance.
Tree is up to date at revision 10807 of branch
http://bzr.squid-cache.org/bzr/squid3/trunk

Why is that?

2) How exactly do I proceed after the bzr checkout?

automake
autoconf
./configure ...

? I'm asking becuase automake is spitting into my face with:

# automake
configure.in:9: required directory ./cfgaux does not exist
configure.in: no proper invocation of AM_INIT_AUTOMAKE was found.
configure.in: You should verify that configure.in invokes
AM_INIT_AUTOMAKE,
configure.in: that aclocal.m4 is present in the top-level directory,
configure.in: and that aclocal.m4 was recently regenerated (using
aclocal).
configure.in:37: required file cfgaux/config.guess' not found
configure.in:37: automake --add-missing' can install config.guess'
configure.in:37: required file cfgaux/config.sub' not found
configure.in:37: automake --add-missing' can install config.sub'
configure.in:48: required file cfgaux/install-sh' not found
configure.in:48: automake --add-missing' can install install-sh'
src/Common.am:29: USE_LOADABLE_MODULES does not appear in AM_CONDITIONAL
compat/Makefile.am:5: src/Common.am' included from here
compat/Makefile.am:12: Libtool library used but LIBTOOL' is undefined
compat/Makefile.am:12: The usual way to define LIBTOOL' is to add
AC_PROG_LIBTOOL'
compat/Makefile.am:12: to configure.in' and run aclocal' and
autoconf' again.
compat/Makefile.am:12: If AC_PROG_LIBTOOL' is in configure.in', make
sure
compat/Makefile.am:12: its definition is in aclocal's search path.
compat/Makefile.am: required file cfgaux/depcomp' not found
compat/Makefile.am: automake --add-missing' can install depcomp'
/usr/share/automake-1.11/am/depend2.am: am__fastdepCC does not appear
in AM_CONDITIONAL
...
