#6 Error in compiling

[ivcha]

I get this error when I try to compile (i.e. install this Arch Linux package):

arg.o: In function `Arg::get_terminal_width()':
arg.cpp:(.text+0x961): undefined reference to `initscr'
arg.cpp:(.text+0x966): undefined reference to `endwin'
arg.cpp:(.text+0x96c): undefined reference to `COLS'
collect2: error: ld returned 1 exit status
Makefile:382: recipe for target 'xstow' failed

My configuration: Arch Linux 3.17.3-1

The question is whether this an error in the source code or in how Arch package defines the build?
