Problem installing Bro

Hi I'm trying to install Bro from the source code in Robin's work branch. When I try the command ' ./ && ./configure && make', BRO Build Tools Setup and Binpac Build Tools Setup go smoothly. but it errors out on Broccoli Build Tools Setup. following is the message.


I'm afraid I cannot say, since AC_PROG_LIBTOOL is in fact used in
Broccoli's, and we're not using a libtool this new on any
of our systems. Sorry.
