请教：使用nios2-gcc编译内核在menuconfig卡住

如题，make menuconfig时出现如下错误：

config/mkconfig > config.in
make -C /root/uClinux-dist-test/config/scripts/lxdialog all
make[1]: Entering directory `/root/uClinux-dist-test/config/scripts/lxdialog'
/soft/nios2/bin/../lib/gcc/nios2-linux-uclibc/3.4.6/../../../../nios2-linux-uclibc/bin/ld.real: cannot find -lncurses
collect2: ld returned 1 exit status

>> Unable to find the Ncurses libraries.
>>
>> You must have Ncurses installed in order
>> to use 'make menuconfig'

make[1]: *** [ncurses] 错误 1
make[1]: Leaving directory `/root/uClinux-dist-test/config/scripts/lxdialog'
make: *** [menuconfig] 错误 2



难道是缺包么？
另外我的nios2-gcc是从朋友那里拷来的一个“绿色”版本，不知道会不会有问题？
如果谁有原版的nios2-gcc安装文件，请发我邮箱一个，网上找了好久没找到可以下载的。
