It should not be a problem to have as many different perls installed as you like; they are designed not to interfere with one another. You should file a bug report for the help2man problem you encountered, assuming a ticket does not already exist for this. Since it has variants for different perls, it should be using the perl you chose; if it doesn't, that's a bug. > 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 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?” Ports that use perl should either depend on the perl5 port (if they don't care about the perl version and don't use any modules) or the perl5.34 port (if they require a more recent perl or they require any perl modules). We cannot move MacPorts to a newer default version of perl than 5.34 until someone contributes module ports for the newer perls. See https://trac.macports.org/ticket/67830 It looks like help2man depends on p5-locale-gettext and someone has already contributed perl 5.36 and 5.38 versions of just that module so variants for those versions of perl could be added to the help2man port.
