Odd Error While Installing Bzip2 in Chroot Environment

Hey y'all. I'm building Bzip2 in Chapter 6 right now, and I'm getting an odd error on installation. Here's the output of "make PREFIX=/usr install".

bzip2: I won't read compressed data from a terminal.
bzip2: For help, type: `bzip2 --help'.
make: *** [Makefile:94: install] Error 1I've looked online, and I'm still not sure what the line about reading compressed data is and what its significance is. What advice would y'all have here?
