help2man configure failure: perl module Locale::gettext required

When attempting to upgrade my tree to 10.6 using the "sudo port upgrade --force installed" method mentioned on the migration page, I get the following error:

oops. let's try that output paste again...

Is it able to build if you clean, uninstall, and install these?

Not sure what you mean by "these", but if you mean p5-locale-gettext and help2man, then the answer is no.

This is one of the possible failure cases that the Migration page mentions. You'll find that ${prefix}/bin/perl is 32-bit and needs to be rebuilt.

Replying to jmr@…:

Well, it says "Note that this method may sometimes fail [...] if ports other than gawk/grep/gsed are used opportunistically". It doesn't specifically mention perl, though I agree perl could be used opportunistically too.

You'll find that ${prefix}/bin/perl is 32-bit and needs to be rebuilt.

Then why didn't MacPorts rebuild it? help2man declares a dependency on perl. p5-locale-gettext, which the output shows was already upgraded, is a member of the perl5 portgroup, which also declares a dependency on perl.

We don't need two tickets for this; duping this one to #21069.
