I'm trying to patch dev-lang/rubinius- so that it will install on my system with sys-devel/llvm-3.1-r1. Based on the bug discussion thread here, it was pointed out that a commit was done to support llvm3.1, here. Using this tip, I was able to download the commit as a patch, and then attempted to apply it using localpatch. However the patch failed with an error message that I've seen before when I've tried to apply a patch that I've found under similar circumstances;
Local patch rubinius- does not fit.

So what does this error message actually mean? How does a patch not fit? Is there something I'm doing wrong when trying to apply this kind of patch? For completeness, here's the patch as I downloaded it and tried to apply it;

I'm not an expert at this, but... Looks like you need to loose the header portion.

Then edit the file paths, example:
--- a/Rakefile
+++ b/Rakefile
to match the paths starting in the workdir, not the "/var/tmp/portage/..." portion. Editing those paths is something I have had to do to make patches work in ebuilds.

GNU patch should handle the posted file as-is, assuming that it is relevant to the targeted code. OP: could you post the context around the error message and explain exactly how you set up the patch to apply? That does not look like the message that Portage would use if you were using /etc/portage/patches. Please show the exact shell commands that one of us would execute to recreate your changes.

After downloading the patch, I renamed it to

and placed it in the following directory;

I then try to emerge rubinius which results in the following short output;
emerge -v rubinius

jasn ...

how are we to know what changes funtoo has made to the epatch_user() function in the eutils.eclass or other indeed other eclasses and portage in general? The error message doesn't seem to be present in the epatch_user() function at least on gentoo. So, your asking in the wrong forum ... I suggest you try funtoo forums.

best ... khay

After some prompting from posting this over on the Funtoo forums, it appears that the patch doesn't work correctly against the dev-lang/rubinius- source. I should have looked at this more closely before posting, because after examining the patch and source, I see that the patch attempts to patch three files that don't even exist in the dev-lang/rubinius- source, vm/llvm/disassembler.cpp, vm/llvm/disassembler.hpp, and vm/llvm/state.cpp. Perhaps that's what generates the error message of the "patch does not fit".

Because it was raised as a possible factor, I wanted to repost to the thread and report that this issue doesn't appear to be Gentoo/Funtoo "difference related". My original question was just asking what the, "does not fit" error message meant, because it isn't very informative. I got the same error message when I applied the patch via my local overlay. However, I was able to see the actual patch output error message after manually attempting to apply the patch.
