Convert perl to package problems

[donald]

• After Convert perl to package #1406 /usr/local/bin/perl was no longer available, but known that many scripts might still use it, a wrapper has been installed manually:

#! /bin/bash
echo "warning: obsolete /usr/local/bin/perl called by" >&2
echo "   $*" >&2
echo "   replace with /usr/bin/perl or /usr/local/system/perl/bin/perl" >&2
exec /usr/bin/perl "$@"

• Because the above warning produced to much noise in some logfiles, we want to use just a symlink or wrapper without warning the next time.
• The wrapper or symlink should go into the perl-wrapper bee package and not be created manually.
• Convert perl to package #1406 made an implicit update of /usr/bin/perl from 5.12.1 to 5.28.1 . A lot of software already uses 5.28.1 or even 5.30.0, so this was not assumed to create many problems and even so, this problems would typically just concern the admin not the users, because the later don't use archaic langugees. However, vacation and twiki failed, which is user visible. So Convert perl to package #1406 had to be undone temporarily
• vacation failed, because omitting parentheses around the list used in a foreach-Loop when the list consisted of a qw-expression only, was historically allowed by the parser but deprecated in 5.14 and made illegal in 5.18 forbidding syntax like for $a qw(a b c) { ... } which needs to be changed to for $a (qw(a b c)) { ... }

vacation is fixed, twiki is more than just a single qw(). Maybe do an update first.

Some modules seem to be gone too. To me it looks like the missing Error.pm causes the initial trouble in elager.

Can't locate Error.pm in @INC (you may need to install the Error module) (@INC contains: /package/twiki/foswiki/lib /project/el
BEGIN failed--compilation aborted at /package/twiki/foswiki/lib/Foswiki.pm line 47.
Compilation failed in require at /project/elager/bin/ElagerTWiki.pm line 7.

[donald]

Yeah, we need to add elager to the list of things to check. But the dependency on Error.pm is from twiki, maybe if twiki is updated, this will go away.

[donald]

twiki is fixed (hopefully) shebangs of scripts changed from #! /usr\/bin\/perl to #! /usr/bin/prun perl-5.12.1-0 perl.

[donald]

Elager also fixed (hopefully): Shebang of /project/elager/htdocs/login.pl changed from #! /usr/local/bin/perl to #! /usr/bin/prun perl-5.12.1-0 perl.
