Hunk failing on simple patch, how should I interpret the rejection file?

Question

I am trying to create a patch that removes the last 20 or so lines from a makefile but am getting "Hunk #1 FAILED at 14." and the following rejection file.

***************
*** 14,35 ****

  host_cpu = @host_cpu@

- if MAC_DARWIN
- carbon = @enable_carbon@
- bin_SCRIPTS = $(launch_scripts)
- install: install-am

-         mv temp $(DESTDIR)$(bindir)/$$i; \
-         chmod 755 $(DESTDIR)$(bindir)/$$i; \
-     done
- endif
--- 14,16 ----

  host_cpu = @host_cpu@

How should I interpret it? I would have thought that the lines 14-16 were a match. The patch is

Sorry, should have done some more digging before asking. The problem was that I was pasting the patch into another file using vim and it was changing the line endings.

I fixed it by saving piping the patch directly to the file using >>

git diff >> my_file
