Build deb packcage for nginx with wsgi support under debian lenny(5.0)

I am not familiar with debian's deb package build system, so I go through the process of building deb package from source at first.

Install packages needed for building nginx

sudo apt-get build-dep nginx
sudo apt-get install fakeroot

Get source code package:

mkdir $HOME/build/nginx -p
cd $HOME/build/nginx
apt-get source nginx

Build it to generate deb package
```
cd nginx-0.6.32
dpkg-buildpackage -rfakeroot
```
Everything goes well, a deb package is generated under $HOME/build/nginx.

Then I continue to build nginx with wsgi support

Checkout latest code of ( mod_wsgi for nginx)

cd $HOME/build/nginx
hg clone http://hg.mperillo.ath.cx/nginx/mod_wsgi/

Edit $HOME/build/nginx/nginx-0.6.32/debian/rules, add additional options to the configure clause:
```
--add-module=${HOME}/build/nginx/mod_wsgi --with-debug
```
Edit $HOME/build/nginx/nginx-0.6.32/debian/conf/nginx.conf, add these two lines to "http" section:
```
include             /etc/nginx/wsgi_vars;
wsgi_temp_path      /var/tmp/nginx_wsgi_temp;
```

Copy file wsgi_vars from wsgi's conf directory to nginx's

cp $HOME/build/nginx/mod_wsgi/conf/wsgi_vars \
   $HOME/build/nginx/nginx-0.6.32/debian/conf/

Edit $HOME/build/nginx/nginx-0.6.32/auto/install, and thses lines to it

test -f '\$(DESTDIR)$NGX_CONF_PATH' \
        || cp conf/wsgi_vars '\$(DESTDIR)$NGX_CONF_PREFIX'
cp conf/wsgi_vars '\$(DESTDIR)$NGX_CONF_PREFIX/wsgi_vars.default'

Everything is ready now, compile nginx and generate deb package as before
```
cd nginx-0.6.32
dpkg-buildpackage -rfakeroot
```
Install the generated deb package with dpkg, it works.

The deb package I built can be downloaded from here.
