Barry Warsaw 9b5ac3efa6 Refinement by Stefan Krah (see issue 11715, msg133194) to exit early if the
dpkg-architecture command is not found on $PATH.  This should fix the failures
on FreeBSD and Solaris, which do not create the target file via I/O
redirection if the command isn't found (unlike Linux and OS X which do).

SUMMARY = """
Python is an interpreted, interactive, object-oriented programming
language. It is often compared to Tcl, Perl, Scheme or Java.
Python combines remarkable power with very clear syntax. It has
modules, classes, exceptions, very high level dynamic data types, and
dynamic typing. There are interfaces to many system calls and
libraries, as well as to various windowing systems (X11, Motif, Tk,
Mac, MFC). New built-in modules are easily written in C or C++. Python
is also usable as an extension language for applications that need a
programmable interface.
The Python implementation is portable: it runs on many brands of UNIX,
on Windows, DOS, OS/2, Mac, Amiga... If your favorite system isn't
listed here, it may still be supported, if there's a C compiler for
it. Ask around on comp.lang.python -- or just try compiling Python
yourself.
