How to upgrade perl 5.8 to 5.10?

[Helmut Schneider]

Hi,

/usr/ports/UPDATING says:

portupgrade -o lang/perl5.10 -f perl-5.8.\*

# BATCH=YES portupgrade -o lang/perl5.10 -f perl-threaded-5.8.\*
--->  Upgrading 'perl-threaded-5.8.9_3' to 'perl-threaded-5.10.1'
(lang/perl5.10)
--->  Building '/usr/ports/lang/perl5.10' with make flags:
-DWITH_THREADS
===>  Cleaning for perl-threaded-5.10.1

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

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

Stop in /usr/ports/lang/perl5.10.

Currently the only solution seems to remove perl.5.8 which as a result
deletes all dependencies which requires *all* ports to be reinstalled.

Did I miss an important detail?

Thanks, Helmut
