This resolves to:

/snap/core/3604/usr/bin/perl
/snap/core/3748/usr/bin/perl
/snap/core/3887/usr/bin/perl
/usr/bin/perl
[download]

Then I did the following:

for var_p in `locate -r /bin/perl$`; do echo $var_p; $var_p -v| grep '
+(v'; perl -le 'print "-" x 150;'; done

It gave me the following results:

This is perl 5, version 22, subversion 1 (v5.22.1) built for x86_64-li
+nux-gnu-thread-multi

According to results, all of them have version 5.22.1
then I did: perl -le 'print for @INC;', it gave me:

/etc/perl
/usr/local/lib/x86_64-linux-gnu/perl/5.22.1
/usr/local/share/perl/5.22.1
/usr/lib/x86_64-linux-gnu/perl5/5.22
/usr/share/perl5

/usr/share/perl/5.22
/usr/local/lib/site_perl
/usr/lib/x86_64-linux-gnu/perl-base
.

None of the paths show 5.20.2, so, I don't get it, where cpan gets it from.
