# bzip2 - block-sorting compressor.
#
# Hand written, not generated: bzip2's Makefile has no DESTDIR support at all -
# PREFIX *is* the destination - so the generated "make" template installed into
# the build host instead of the package directory and failed. It also does not
# build a shared library by default, which everything linking -lbz2 expects.
