Sorry, My assumption was that you are using DEY and not DEL. I do not have access to the DEL DVD image right now so I cannot give you exact path, but I can give a similar example of a different package used in DEL (openntpd):
You can see sources for openntpd we used on DVD:
DVD\toolchain\packages\openntpd-3.9p1.tar.gz
You can see how we configured and built it also on DVD:
DVD\toolchain\del_toolchain\packages\openntpd\Makefile.in:
$(PACKAGE_DIR)/.configured: $(PACKAGE_DIR)/.unpacked
( cd $(PACKAGE_DIR); autoconf; autoheader; rm -f config.cache; \
./configure \
--prefix=/usr \
--sysconfdir=/etc \
--mandir=/usr/share/man \
--with-mantype=man \
$(if $(findstring $(TARGET),host),,--host=arm-linux --disable-strip) \
--with-adjtimex \
--with-builtin-arc4random \
);
