Rebuilding Debian package from source

[Joshua Schaeffer <jschaeffer0922@gmail.com>]

I'm trying to rebuild the nginx-extras package from Jessie and I'm running into an error when I run debuild. I want to add a module to Nginx. I've just been following this to rebuild the package: https://raphaelhertzog.com/2010/12/15/howto-to-rebuild-debian-packages/

Here is what I've done:

1. Downloaded the source using apt.
• apt-get source nginx-extras
2. Built the dependencies for the package
• apt-get build-dep nginx-extras
3. Updated the debian/rules file to include my module
4. Added my module to the debian/modules directory
5. Ran debuild to compile the package.
• debuild -us -uc

When I run the debuild command I get an error about no Test/nginx-1.6.2-5_deb8u2/auto directory existing. As the error suggests it doesn't exist, but I'm not sure how to fix it. Creating the directory just leads to another error. Would anybody be able to tell me why I'm getting this error and how to fix it. I do have devscripts installed on the machine.
