There is currently no patch for ns-2.33 and since Eurane is not supported anymore, there probably never will be. You have two options.
1) Download ns-2.30 and patch with existing eurane patch. If you need something introduced in later versions of ns-2, you cannot use it.
2) Patch an existing ns-2.33 with the eurane patch for ns-2.30. This could result in difficulties which you must manually resolve.
The patching procedure is documented in the manual, section 2.3.
A patch is distributed in something called a diff-file, hence the file extension .diff. Gzip then adds the extension .gz. Before pathing the .diff.gz file needs to be uncompressed using gunzip. The result will be the diff-file.

What gives an error? A patch file should not be "opened", see the eurane manual for correct usage, or the patch man page, or google for "unix command patch" or similar.

A clean version is a version not messed up by changes, builds etc. A fresh downloaded version is a clean version.

This is because ns-2 (without the patch) does not understand the instructions in those tcl files. You need the patch to be able to run the tcl files.
