libbegemot port to FreeBSD 4.x

[Andrey V. Elsukov]

Hello!

I try to make port of libbegemot on FreeBSD 4.x.
But i have one problem - freebsd 4.8 have not definition of PRIu64 in 
inttypes.h. I tried patch:

I run following commands after patching:
aclocal19 -I /usr/local/share/libtool15/libltdl/
autoconf259

This works. But, how to make this automatic in port?
My Makefile:

# New ports collection makefile for:    libbegemot

.include <bsd.port.mk>

This fails with message:
aclocal: unrecognized option -- `-I /usr/local/share/libtool15/libltdl/'
Try `aclocal --help' for more information.
*** Error code 1

What i can do?
Thanks.
