Could you give an example ???
For the two ports I've personal experience with my modification seems to
work perfectly

I'm of course aware, than when switching / upgrading to another version
of Perl all of the ports defined in this way will have to be rebuilt,
but that's no different from what we already have with the p5.xx-{mod}
ports.

When I personally swithced from Perl 5.12 to Perl 5.14 I had to do this:

port -s install perl5.14

# find & upgrade from p5.12 -> p5.14
port installed \
| grep p5.12 \
| while read portname version active
do
    port -f deactivate ${portname}
    port -f -s install ${portname/12/14}
done

# use perl5 port to switch to perl 5.14

# use cpan to initialise again
cpan
port -f uninstall perl5.12

# find & upgrade ports dependent on a p5.12 module
( ( port installed \
| grep p5.12 \
| while read portname version active
do
    port -q dependents ${portname}
done ) \
| sort \
| uniq \
| grep -v p5.12 ) |
xargs -n1 port -s -n upgrade --force

# this is possibly overkill
cpan -l | while read module version
do
    cpan -f -i ${module}
done

# force uninstall inactive ports
port -q installed \
| sed -E -e '/active/d' \
| xargs -n2 port -f uninstall
