PowerTop's README states

in addition to that, PowerTOP requires the following components:

pciutils-devel (is only required if you have PCI)
ncurses-devel (required)
libnl-devel (required)
kernel version => 2.6.38

But if you're sure that it's not needed then you can try

Code:

make NCURSES_LIBS=

You're trying to build a source tree that either a) requires curses or b) thinks that it does, hence the -lncurses flag.

Solutions:

a) Install ncurses.
b) Remove that flag from the makefile (or whichever build system you're using)
