Perl upgrade problem...

[Peter Harrison]

Up till now I've kept Perl on my machine at 5.8.9. I now see from UPDATING that upgrading to 5.10 is recommended.

However, when I follow the instructions, I get the following error:

laptop# portupgrade -o lang/perl5.10 -f perl-5.8.9_3
--->  Upgrading 'perl-5.8.9_3' to 'perl-5.10.1' (lang/perl5.10)

===>  perl-5.10.1 conflicts with installed package(s): 
      perl-5.8.9_3

      They install files into the same place.
      Please remove them first with pkg_delete(1).

** Fix the problem and try again.

Any advice on how to fix?

Thanks in advance.
