esi support / building squid3

hi,

as mentioned earlier i'm working on squid3/esi support for zope3.
yay! i got my first template assembled a few hours ago, but soon i
ran across http://www.squid-cache.org/bugs/show_bug.cgi?id=1566
(i've been running squid-3.0.PRE5)

now i'm trying to get CVS head running, but i fail on bootstrapping it:

lovely@nigiri:~/src/squid3-cvs$ ./bootstrap.sh
automake : -1.9
autoconfg:
libtool :
Bootstrapping
configure.in:34: error: possibly undefined macro: AC_LTDL_DLLIB
       If this token and others are legitimate, please use
m4_pattern_allow.
       See the Autoconf documentation.
autoconf failed
Autotool bootstrapping failed. You will need to investigate and correct
before you can develop on this source tree

any suggestion?

thanks

jodok
