Why is the GNU patch not suitable for this diff?

Question

G'day

Edit: I just thought that I would say that this rather long question has now been fixed due to the fact that Adam Hood answered below if you just slip through.

I have added a patch to add in Apache 2.2.14, and one unified diff does not fix the file at all. I am using GNU patch 2.5.4.

I need to ignore the spaces because the original patch did not execute well, i.e. many of the differences seem to translate into tabs → spaces. These kinds of differences are even less useful since the patch file has been modified somewhere along the delivery chain, for example. svn repository, Jira system, web interface, etc., so that all tabs were converted to spaces anyway!

I am using the Solaris 10 command:

/usr/bin/gpatch --verbose --ignore-whitespace -p1 -d . \
    <mod_cache.diff

and output:

...

Hmm...  The next patch looks like a unified diff to me...
