Considering upstream is dead (web site vanished in 2007) and it's even been removed from FreeBSD ports, I think it might be time to consider this one dead.
Adding the DEB_HOST_MULTIARCH would seem to help, but then it doesn't appear the entire build system pays attention to SYS_INCLUDES. Then there are some includes that seem to be missing even after you fix the path. -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
