# MOD_PYTHON_VERSION, MOD_PYTHON_SITE and MOD_PYTHON_SOURCE define

# MOD_PYTHON_DIR is the directory which is created when the source
# archive is unpacked.
# MOD_PYTHON_UNZIP is the command used to unzip the source.
# It is usually "zcat" (for .gz) or "bzcat" (for .bz2)
#
# You should change all these variables to suit your package.

# applied in this target as required.
#
# This target also configures the build within the build directory.
# Flags such as LDFLAGS and CPPFLAGS should be passed into configure
# and NOT $(MAKE) below.  Passing it to configure causes configure to
# correctly BUILD the Makefile with the right paths, where passing it
# to Make causes it to override the default search paths of the compiler.
#
# If the compilation of the package requires other packages to be staged
# first, then do that first (e.g. "$(MAKE) <bar>-stage <baz>-stage").
#
# Note: configure breaks if bash 3.1 is installed!
