bootstrap's function find_tool

[Thomas Treichl]

Hi everybody,

a month ago I was still working on an older OS X 10.4 system and tried 
to compile recent sources of GNU Octave which now uses the bootstrap 
file. I failed with a local copy of gnulib (I used the option 
--gnulib-srcdir=<path>) because I didn't have any of the tools gsha1sum, 
sha1sum etc. We started a discussion about it here


http://old.nabble.com/bootstrap%2C-sha1sum%2C-gsha1sum-and-such-things--to26791930.html

No my suggestion to the GNU Octave project was to comment out the line

  find_tool SHA1SUM sha1sum gsha1sum

which of course is not the best solution. In our discussion we found out 
that the best solution might be to check for the tools right before they 
are really used for the first time - if given the option 
--gnulib-srcdir=<path> none of these tools should be needed, right? Is 
it possible that you make such a change please?

Meanwhile I personally changed to OS X 10.6 and must say now, that we 
have such a tool which is called "shasum" and is part of the OS itself at

  MyMac$ which shasum
  /usr/bin/shasum

Maybe this should be added to the list of the find_tool line.

Thank you very much

  Thomas
