And 

$ pod2text -c /usr/local/texlive/2017/texmf-dist/scripts/texlive/tlmgr.pl | less -R

gives nice coloured output

in fact compared to "man tlmgr", what is underlined in the latter appears
coloured in the former, so the output from using

$ pod2text -c /usr/local/texlive/2017/texmf-dist/scripts/texlive/tlmgr.pl | less -R

is even fancier than the one from

$ man tlmgr 

or 

$ /opt/miniconda3/bin/pod2usage -verbose 2 /usr/local/texlive/2017/texmf-dist/scripts/texlive/tlmgr.pl

the latter two being equivalent

Thus "pod2text" looks OK, but "pod2usage" possibly has a problem
in the Perl 5.24 I got from MacPorts

Using pod2text or the  /opt/miniconda3/bin/pod2text produce both same or similar
output contrarily to what happens with pod2usage

$ which -a pod2text
/opt/local/bin/pod2text
/opt/miniconda3/bin/pod2text
/usr/bin/pod2text

Best,
