Comment:

 I am able to reproduce the problem if I install perl5 with +perl5_36.

 I believe the problem is the pulseaudio port which declares a dependency
 on `port:p${perl5.major}-xml-parser` without first setting
 `perl5.branches` to the desired version. That means it will inherit the
 perl version from whatever you've selected with the perl5 port. Ports
 shouldn't do that.

 In fact, pulseaudio probably shouldn't haven't a dependency on XML::Parser
 at all. It has a dependency on intltool, and intltool erroneously adds
 code to projects' configure scripts that check for the presence of
 XML::Parser with the default perl. Ports should `autoreconf` to rebuild
 their configure scripts with our patched version of intltool that doesn't
 do that unnecessary and counterproductive step. The upstream bug report,
 which upstream has not acknowledged or fixed in over ten years, is
 https://bugs.launchpad.net/intltool/+bug/1197875.
