Actually, it should, but the syntax used in the metaunit to generate that part of Configure (Loc.U) us *only* used in Loc.U, and I have not found either the documentation of that syntax, nor a reason why tail is not put inside the list in Configure. The list that should be probed is: awk cat chgrp chmod chown comm cp echo expr find grep ls mkdir mv rm sed sleep sort tail touch tr uniq The list that ended up in Configure: awk cat chmod comm cp echo expr grep ls mkdir rm sed sort touch tr uniq Why chmod, but not chgrp and chown? Why grep, but not find? Why rm, but not mv? 37604 100755 -r-x 1 root 240412 13 Sep 2005 02:44 /usr/bin/awk -> /bin/awk -> gawk -> /bin/gawk 37604 100755 -r-x 1 root 240412 13 Sep 2005 02:44 /bin/awk -> gawk 40746 100755 -r-x 1 root 19220 31 Jan 2006 17:28 /bin/cat 40771 100755 -r-x 1 root 37020 31 Jan 2006 17:28 /bin/chgrp 40772 100755 -r-x 1 root 36044 31 Jan 2006 17:28 /bin/chmod 40776 100755 -r-x 1 root 40284 31 Jan 2006 17:28 /bin/chown 42727 100755 -r-x 1 root 17804 31 Jan 2006 17:28 /usr/bin/comm 40777 100755 -r-x 1 root 61548 31 Jan 2006 17:28 /bin/cp 42699 100755 -r-x 1 root 16532 31 Jan 2006 17:28 /bin/echo 42736 100755 -r-x 1 root 23456 31 Jan 2006 17:28 /usr/bin/expr 40451 100755 -r-x 1 root 76196 9 Sep 2005 18:26 /usr/bin/find 41057 100755 -r-x 1 root 135276 9 Sep 2005 18:27 /usr/bin/grep -> /bin/grep 41057 100755 -r-x 1 root 135276 9 Sep 2005 18:27 /bin/grep 42704 100755 -r-x 1 root 82640 31 Jan 2006 17:28 /bin/ls 42705 100755 -r-x 1 root 26840 31 Jan 2006 17:28 /bin/mkdir 42707 100755 -r-x 1 root 67876 31 Jan 2006 17:28 /bin/mv 42709 100755 -r-x 1 root 36236 31 Jan 2006 17:28 /bin/rm 41229 100755 -r-x 1 root 41540 9 Sep 2005 18:08 /usr/bin/sed -> /bin/sed 41229 100755 -r-x 1 root 41540 9 Sep 2005 18:08 /bin/sed 42711 100755 -r-x 1 root 16916 31 Jan 2006 17:28 /bin/sleep 42712 100755 -r-x 1 root 49972 31 Jan 2006 17:28 /usr/bin/sort -> /bin/sort 42712 100755 -r-x 1 root 49972 31 Jan 2006 17:28 /bin/sort 42770 100755 -r-x 1 root 39480 31 Jan 2006 17:28 /usr/bin/tail 42716 100755 -r-x 1 root 34276 31 Jan 2006 17:28 /usr/bin/touch -> /bin/touch 42716 100755 -r-x 1 root 34276 31 Jan 2006 17:28 /bin/touch 42774 100755 -r-x 1 root 31592 31 Jan 2006 17:28 /usr/bin/tr 42778 100755 -r-x 1 root 26004 31 Jan 2006 17:28 /usr/bin/uniq > I'm not sure why these empty variables are included in Config{.pm,_heavy.pl} > if they're not actually searched for--forwarding to p5p for comments.

And if you want a more generic approach, you can create a Policy.sh and put the defines in there, so you do not have to add all the -D.... to Configure all the time. > This presumes that any program using these variables does so as: > > my $tail = $Config{tail} || 'tail'; > my $sendmail = $Config{sendmail} || '/usr/sbin/sendmail'; -- H.Merijn Brand Amsterdam Perl Mongers (http://amsterdam.pm.org/) using & porting perl 5.6.2, 5.8.x, 5.9.x on HP-UX 10.20, 11.00, 11.11, & 11.23, SuSE 10.0, AIX 4.3 & 5.2, and Cygwin. http://qa.perl.org http://mirrors.develooper.com/hpux/ http://www.test-smoke.org http://www.goldmark.org/jeff/stupid-disclaimers/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
