dvtm.patch alters the config.mk file as there is no configure file. dvtm-vt.patch is a stopgap measure to let it build - I have had dvtm crash on me, after closing a pane, then trying to change the pane layout. What's altered is changing waddnwstr to waddnstr. Until ncurses is built with wide character support, this won't build without this ugly hack.
