[Bro] Errors while building pybroccoli?

[Stephen Chan]

Hi,
I just checked out the python bindings for broccoli and tried building 
it against Bro 1.3.2 using the suggested "python setup.py install". I am 
using python 2.4.3 and gcc 4.1.2 on CentOS 5

Unfortunately the build just results in a few screens of compilation 
errors and warnings. Looking at the Makefile, I decided to try 
regenerating the swing bindings and running setup.pu again. This cut 
down the number of errors to only a single screenful. Here's what I'm 
getting:

The first error "broccoli_intern_wrap.c:2762: error: expected 
declaration specifiers or ‘...’ before ‘BroEvMeta’" references this:
// C-level event handler for events. We register all events with this 
callback,
// passing the target Python function in via data.
void event_callback(BroConn *bc, void *data, BroEvMeta *meta)
{
...

I don't see any declaration for the BroEvMeta type anywhere. There's a 
reference to this type in 
http://svn.icir.org/bro/trunk/bro/aux/broccoli/test/broping.c in the 
bro_pong_compact() declaration:

static void bro_pong_compact(BroConn *conn, void *data, BroEvMeta *meta)

However signature in my version of the broping is:
static void bro_pong_compact(BroConn *conn, void *data, int num_args, 
BroEvArg *args)

I'm guessing that things have changed since the 1.3.2 release and that 
the python bindings are against the current code base. Is that true?
Do I need to download the latest bro source tree via subversion to use 
the pythong bindings?
