Creating a new Freebsd port

I am trying to create a new freeBsd port for cogapp 2.2 . I use the following makefile which actually fetches the tar.gz as expected but does not use easy install to install the package.

# New ports collection makefile for:    cogapp
# Whom:                 Karthick   
#
# $FreeBSD: ports/devel/py-virtualenv/Makefile,v 1.21 2011/03/12 23:53:13 nivit Exp $
#

PORTNAME=       cogapp
PORTVERSION=    2.2
CATEGORIES=     devel python
MASTER_SITES=   http://pypi.python.org/packages/source/c/cogapp/

MAINTAINER=     xyz@FreeBSD.org
COMMENT=        cog port

USE_PYDISTUTILS=        easy_install

.include <bsd.port.mk>

It rather throws the following error

 ===>  Vulnerability check disabled, database not found
===>  License check disabled, port has not defined LICENSE
===>  Extracting for cogapp-2.2
=> No checksum file (/tmp/cogapp-2.2/distinfo).
===>  Patching for cogapp-2.2
===>  Configuring for cogapp-2.2
===>  Building for cogapp-2.2
make: cannot open Makefile.
*** Error code 1

Stop in /tmp/cogapp-2.2.

Can anyone suggest me a solution for this!

Solution

It's worked for me with these changes:

USE_PYTHON=yes
USE_PYDISTUTILS=yes

And while i'm there:

USE_PYTHON defines which python versions are working with this port. If it's "yes", then all python version are supported.
Run 'make makesum' to create distinfo file for your port.
You also would need to create packing list (a list of files, that are installed by port). For this i'm using helper script written by FreeBSD developer amdmi3: link For this, run 'pt i && pt plist' inside your port dir.
