  Branch: HEAD                             Handle: 2007113018030400

  Modified files:
    rpm                     configure.ac

  Log:
    indicate that the 'lzma' here is the command line tool and use
    sub-shell constructs to more portably support the situation where no
    lzma(1) is in PATH at all (and hence the shell itself already
    complains with a confusing 'lzma: file not found')
