So put patches in files/, or use REINPLACE_CMD. Read the Porter's Handbook for instructions on how to do this.

Most likely, there's no Makefile in WRKSRC. Either override do-install, add in a working Makefile, or change WRKSRC to somewhere with a Makefile.

"blubee", you have a habit of asking lots of questions and not giving us the Makefile. It's very hard to give you answers without all the context. Please, give us the Makefile when you are asking for help with a Makefile.
