Fixed in [4d26619fceac0fddaf49ce9c0910fe2705600ba9/macports-ports]

[mascguy (Christopher Nielsen)]

Zhenfu, I looked at your fix, and I have some concerns.

In particular, if the port doesn't build properly with perl 5.32 or 5.34 active, then it should be fixed to ensure it does.

Otherwise, this is going to cause headaches for numerous users, as it's common to have a variety of Perl 5 versions installed and active at the same time.

I've also built po4a numerous times with 5 32 and 5.34 active, without an issue.

Did you look at why the port is finding 5.32 and 5.34 components?

[mascguy (Christopher Nielsen)]

Also bear in mind that the license prevents use of buildbot binaries for po4a, so users are going to be bitten by this on every update.

[i0ntempest]

Okay you can revert my change for now, I’ll investigate more on this later.

Okay this is actually caused by perl5 +perl5_34 being active on my system which contains the symlink perl->perl5.34, not the perl5.34 port itself. I'm guessing it's the po4a configure script using perl executable if present, we should set it to use perl5.30 or whatever is used in the port.
