Question [Q] ncurses requirement but no ncurses in sources

Hi All.
I am trying to compile an excutable for Android JB. the executable uses (in the sources and Android.mk file) libncurses.
But there is not ncurses nor libncurses in the tree, only in prebuilts/gcc/linux-x86/....glibc-2.7-4.6/sysroot/usr/lib/libncurses.so

What should i do??

Thanks
