several ports cannot be installed due to a Perl circular dependency hell...

eg:

sudo port -v -s install maxima

Error: The following dependencies were not installed because all of
them have unmet dependencies (likely due to a dependency cycle):
p5.34-authen-sasl p5.34-net-smtp-ssl p5.34-cgi
p5.34-pod-coverage-trustpod p5.34-test-simple p5.34-pod-eventual
p5.34-mixin-linewise p5.34-sub-exporter p5.34-data-optlist
p5.34-params-util p5.34-config-autoconf p5.34-file-slurper
p5.34-test-warnings p5.34-cpan-meta-check p5.34-module-pluggable
