[help2man variant with perl5_40, use MacPorts with single Perl port]

[Maxim Abalenkov]

Dear all,

How are you? I hope all is well with you. I need help please. I recently ran into trouble with a command-line tool called ‘help2man’:

HELP2MAN starpu_env.1
Encode.c: loadable library and perl binaries are mismatched (got handshake key 0x10200080, needed 0xfb80080)

I assume, this happens because I have multiple Perl installations on my system: Apple’s, MacPorts’ and my own compiled from source.

When I look at all possible port variants for help2man I see:

sudo port variants help2man
Password:
help2man has the variants:
   perl5_28: Use MacPorts perl5.28
     * conflicts with perl5_30 perl5_32 perl5_34 perl5_36 perl5_38
   perl5_30: Use MacPorts perl5.30
     * conflicts with perl5_28 perl5_32 perl5_34 perl5_36 perl5_38
   perl5_32: Use MacPorts perl5.32
     * conflicts with perl5_28 perl5_30 perl5_34 perl5_36 perl5_38
[+]perl5_34: Use MacPorts perl5.34
     * conflicts with perl5_28 perl5_30 perl5_32 perl5_36 perl5_38
   perl5_36: Use MacPorts perl5.36
     * conflicts with perl5_28 perl5_30 perl5_32 perl5_34 perl5_38
   perl5_38: Use MacPorts perl5.38
     * conflicts with perl5_28 perl5_30 perl5_32 perl5_34 perl5_36
   universal: Build for multiple architectures

Would it be possible to provide another help2man variant that would use perl5_40?

This brings me to a more general question. Is one version of perl5_XY enough to power all other MacPorts that depend on a Perl port or do we really need perl5_34 for one port A and perl5_36 for another port B? Is it possible to bring ‘law and order’ into a MacPorts installation and say: “Dear ports, please use the one and only Perl port v5.40?” I’m sure someone sometime ago has already asked this question, but I didn’t understand the answer that time. Thank you for your help and have a wonderful day ahead!
