Re: Script errors in libtool on Darwin

[Timothy J. Wood]

  Oh please.  Give me a little credit :)

  'head' certainly is installed.

  The problem is that head is getting passed a bogus empty argument 
because $expore_symbols isn't set yet.  Thus, the 'head' command 
embedded in the script below is getting called when it is parsed rather 
than being considered quoted.

  You can tell this is the case by the pair of colons after the 'head' 
in the error.  The filename is supposed to go before the second colon.
