If there are any objections, I do not insist on anything for Linux, but this does fix the issue for me.

help2man depends on perl5.34. perl5.34 provides the perl5.34 executable. The perl5 symlink is provided by the perl5 port. If you want to use the perl5 symlink here you have to depend on the perl5 port.

@reneeotten @ryandesign Yeah, will do this tomorrow. Sorry for a delay, Linux is not really a priority, but I want basic ports to work.

@reneeotten Done, sorry for a delay here.

@reneeotten Done, sorry for a delay here.

You mixed up two changes in the last commit and the commit message does not reflect that. The "perl5" dependency for "autoconf" should go in the first commit.
