Hi! I've just start compiling util-linux-2.11o and stuck on some errors

cc -s main_losetup.o ../lib/xstrncpy.o -o losetup
cc -O -pipe -O2 -mcpu=i486 -fomit-frame-pointer -I../lib -Wall -Wmissing-prototypes -Wstrict-prototypes -I/usr/include/ncurses -DNCH=0 -D_FILE_OFFSET_BITS=64 -DSBINDIR=\"/sbin\" -DUSRSBINDIR=\"/usr/sbin\" -DLOGDIR=\"/var/log\" -DVARPATH=\"/var\" -DLOCALEDIR=\"/usr/share/locale\" -s pivot_root.c -o pivot_root
/tmp/ccpBDMPi.o(.text+0x18): In function `pivot_root':
: undefined reference to `errno'
collect2: ld returned 1 exit status
make[1]: *** [pivot_root] Error 1
make[1]: Leaving directory `/root/util-linux-2.11o/mount'
make: *** [all] Error 1

What I need to do to compile util-linux???
