irssi needs perl build fixes

[dgilman (David Gilman)]

First, the port may need a revbump. The current binary is linked against perl5.28 but the perl5 port is installing perl5.34 now.

Next, in my own experimentation, I tried to move it to the Perl port group and link it against perl 5.32 and perl 5.34 to test it out. I tried a few things but the configure script is consistently finding the perl 5.34 installation and linking against that, even if perl 5.32 is explicitly requested in the portgroup.

Irssi 1.4 will be the last series to support Autotools ./configure for building.

Irssi is switching to the meson build system, but version 1.4.1 does not build on macOS 12, see ​https://github.com/irssi/irssi/issues/1397.

Back to the perl linking issue, I think we can add a dependency on perl5.28 for now and wait for a fix of the meson build.

irssi: link to perl5.28

Closes: #65466

[jmroot (Joshua Root)]

That didn't work:

% otool -L irssi-1.4.1_1+perl.darwin_20.x86_64/opt/local/bin/irssi
irssi-1.4.1_1+perl.darwin_20.x86_64/opt/local/bin/irssi:
	/opt/local/lib/perl5/5.34/darwin-thread-multi-2level/CORE/libperl.dylib (compatibility version 5.34.0, current version 5.34.0)

[jmroot (Joshua Root)]

I would suggest something like this:

irc/irssi/Portfile

                     --with-perl=no

 }

A couple of other points: I'm not sure it's even desirable to use a custom path with --with-perl-lib, it may be better to set it to vendor? Also, perllocal.pod should not be installed.

Could you explain what vendor is?

[jmroot (Joshua Root)]

It's a perl thing, which the irssi configure script can use. The short version is that there are a few different places that perl looks for modules, which are intended to be used by different parties: perl for modules that ship with perl, vendor for the distro or package manager, and site for sysadmins.

Just updated perl5 and seeing this issue as well.

Encode.c: loadable library and perl binaries are mismatched (got handshake key 0xc500080, needed 0xf880080)

[l2dy (Zero King)]

I have perl5 @5.28.3_0+perl5_28 installed and that's why it was linking to perl5.28 on my Mac. I will incorporate the patch Joshua suggested. Thanks!
