error while compiling on FreeBSD 4.7-release

[Didier Wiroth]

Hey,
(to be honest I'm a *NIX newbie)
I'm using FreeBSD 4-7-RELSEASE with xfce3
I've download the xfce4 sources! When I start/try to compile libxfcegui4 I
get the following error:

Making all in libxfcegui4

Running autogen.sh doesn't work either, it gives the following error
message:

You should update your `aclocal.m4' by running aclocal.
aclocal: not found
-----------------------------------------end of output----------------------

Here is some additional info! I have the following ports/packages installed:
gtk-1.2.10_9
gtk-2.0.9
gtk-engines2-1.9.0
gtk-xfce-engine-2.0.10
autoconf213-2.13.000227_5
automake14-1.4.5_9
libxml-1.8.17_1
libxml2-2.4.28_1
xfce-3.8.18_1

Can someone help me?

(sorry if this is a repost! I had little problem and I do not know if you
have received this message previously!)
Thanks!
Didier
