[SOLVED]How to apply a patch- first attempt

Question

I need to apply a patch to python2-pillow, which was kindly created by manisandro, to allow my HP Officejet 6700 scanner to work.  I'm following the directions at Patching in ABS.  I already have the python2-pillow package installed via pacman.  I generated the md5sum for the patch by copying and pasting the text into gedit and saving it locally as a .diff file.  I then ran md5sum on the file.  The following is a copy of my PKGBUILD:

When I run makepkg I get an error saying I am missing several dependancies: tk, python2-setuptools.  I don't get this error if I reinstall the package using pacman.  Shouldn't the dependancies be the same?  It also seems to be packaging python-pillow rather than python2-pillow.  Is there a way to fix this?
Thanks for any help.

Fixed checksum problem.  The makepkg had worked in part the the .diff file was in the source directory.  I ran md5 on that and it worked.  However, new problem:
==> Starting build()...
/home/sl/abs/pillow/PKGBUILD: line 21: cd: cd /home/sl/abs/pillow/src/Pillow-2.3.0: No such file or directory
==> ERROR: A failure occurred in build().
    Aborting...
However,
[sl@localhost pillow]$ cd /home/sl/abs/pillow/src/Pillow-2.3.0
[sl@localhost Pillow-2.3.0]$
Changing permissions to 777 didn't help.
