SOLVED in 7.2: Perl problems on FreeBSD (again)

[Jose Amengual M]

Hi Guys.

I saw some emails about perl 5.10.1 giving errors when running  
mailscanner, I had the same problem and I follow the instructions  
below but it din't work for me, but finally after 2 days of work I  
found the solution!!!.

This is working 7.2 should work on 8.0.

if you have already mailscanner installed don't worry, portupgrade can  
do all the job for you :).

1.- Remove old perl version :
pkg_info|grep perl ( copy the exact name of you perl version like  
perl5.10.1 )
pkg_delete -f perl5.10.1

2.- Install old perl.
pkg_add -r ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages-7.2-release/lang/perl-5.10.0_2.tbz

3.- Clean up any work directory
portsclean -C

4.- Update pkgdb add upgrade any perl package
pkgdb -Ff
portupgrade -fr perl ( this is going to upgrade everything that uses  
perl including mailscanner).
perl-after-upgrade && perl-after-upgrade -f

After that the error was gone and everything was working fine.

I was in the process of deciding of going towards mailscanner or  
amavisd-new and I decided to use mailscanner because was easier to  
configure and I expend 2 days fixing a problem with perl that I didn't  
have on amavis :).

I hope this help.

Thanks.

Jose Amengual.
