qmail打补丁程序时出错！！

那些花儿

我的系统是fc5的，其它一切正常，在安装qmail补丁程序时出错！希望高手帮忙看看，在fc4下编译也正常，就是在fc5下过不去！

#cd /home/pkg/netqmail-1.05/netqmail-1.05
#bunzip2 -c /home/pkg/qmail-toaster-0.7.2.patch.bz2 | patch -p0
#make clean
#make

下面是最后的一段代码！

( ./compile trysalen.c >/dev/null 2>&1 \
&& echo \#define HASSALEN 1 || exit 0 ) > hassalen.h
rm -f trysalen.o
./compile ipme.c
./compile ndelay.c
./compile ndelay_off.c
./makelib ndelay.a ndelay.o ndelay_off.o
( ( ./compile tryrsolv.c && ./load tryrsolv dns.o \
ipalloc.o strsalloc.o ip.o stralloc.a alloc.a error.a fs.a str.a \
-lresolv `cat socket.lib` ) >/dev/null 2>&1 \
&& echo -lresolv || exit 0 ) > dns.lib
rm -f tryrsolv.o tryrsolv
./compile tls.c
