Tweakings to find the bzip2 distribution

Useful Environment variables

Set these in the environment prior to running "perl Makefile.PL".

BUILD_BZLIB=Test
BZLIB_LIB=
BZLIB_INCLUDE=
BZLIB_BIN=

Set BZLIB_INCLUDE to the directory with bzlib.h in it. There is no default.

Set BZLIB_LIB to the directory with libbz2.a in it. There is no default.

Set BZLIB_BIN to the directory with the bzip2 command in it. There is no default.

BUILD_BZLIB is a flag variable to control the building of the internal, encapsulated version of bzip2 1.0.2. The default is BUILD_BZLIB=Test.

BUILD_BZLIB=1

• Means use the internal bzip2 distribution.

BUILD_BZLIB=0

• Means don't. ever.

BUILD_BZLIB=Test
* Means try to compile a short program (show_bzversion.c) with the standard perl xs compile stuff, plus the settings for BZLIB_INCLUDE and BZLIB_LIB, if any. If it fails, use the internal bzip2. If it succeeds, rely on the system bzip2.

The defaults for these environment variables are in config.in.
