The key point is the setting of PERL5LIB, it points to directories with my private additions, not to those nonstandard versions. It may happen that your incomplete installation sees files from another version which may cause problems. I would suggest to start with verification of environment settings, especially the variables related to perl.

Hi Zdenek,

it seems I have indeed a mess,

$ which -a perl

$ which -a perldoc

$ echo $PERL5LIB

and the latter is a Fink location.

Thus I have (at least) 3 user installs of Perl:

1) the MacPorts one in /opt/local

2) the Anaconda one in /opt/miniconda3

3) the Fink one in /sw/

for the Fink I found


which needs to be invoked under this name

there are repertories

/sw/lib/perl5/5.12.4 and /sw/lib/perl5/5.16.4

the MacPorts has


$ env | grep PERL

in view of the above I tried

$ export PERL5LIB="/opt/local/lib/perl5"

$ tlmgr help

no success


$ export PERL5LIB="/opt/local/lib/perl5/5.24"

no success either

$ unset PERL5LIB

no success either

Right now I have reached the stage where I know that
"man perlrun" is where Perl env variables are documented,

thus now I think I only have to learn Perl and then report back ;-)

(be patient ... if I knew how to trace the binaries in use from
"tlmgr help" I would be better-armed)
