The quilt mode for emacs has seen some changes lately. See the following quotation from the changelog for details. I suggest bumping the ebuild. After adjusting the names of the patch files from ${P} to ${PN}-0.45.4, the current ebuild works for 0.46.2. quilt-el (0.46.2) * fix bad file permissions * remove unnecessary files on patches/ * clean patches directory on `make clean' -- Satoru Takeuchi <...> Fri, 03 Jul 2009 15:34:40 +0900 quilt-el (0.46.1) * honor quilt patches directory * return to cd if shell command is failure * fix colliding name space by nested function * introduce quilt-cmd-to-list * support multiple quilt tree -- Satoru Takeuchi <...> Mon, 22 Jun 2009 20:13:57 +0900 quilt-el (0.45.5) * simplify quilt-revert * fix quilt-dir if default directory is nil * optimize quilt-revert * change maintainer's email address -- Satoru Takeuchi <...> Thu, 28 Feb 2008 23:27:45 +0900
Thanks for your bug report. It is bumped in CVS.
