From Jeffrey Morlan: pst_build_id_ptr and pst_build_desc_ptr require that the first child of a BTree page have the same starting ID as itself. This is not required by the spec, and is not true in many real-world PSTs (presumably, the original first child of the page got deleted). Because of this, many emails are not being extracted from these PSTs. It also triggers an infinite loop in lspst (a separate bug, also fixed)

# SYNOPSIS
#
#   AX_PYTHON
#
# DESCRIPTION
#
#   This macro does a complete Python development environment check.
#
#   It recurses through several python versions (from 2.1 to 2.5 in this
#   version), looking for an executable. When it finds an executable, it
#   looks to find the header files and library.
#
#   It sets PYTHON_BIN to the name of the python executable,
#   PYTHON_INCLUDE_DIR to the directory holding the header files, and
#   PYTHON_LIB to the name of the Python library.
#
#   This macro calls AC_SUBST on PYTHON_BIN (via AC_CHECK_PROG),
#   PYTHON_INCLUDE_DIR and PYTHON_LIB.
