What is the 'perl-dynamic' executable

Investigating an issue with multiple Perl installations on our (HP UX IA64 system), I came across an executable called perl-dynamic. What is this and what exactly does it do?

More importantly, how do I know which perl executable it actually points to (we have multiple versions mixing version numbers and architectures installed).

bash-4.4$ ll /usr/bin/perl    
lrwxr-xr-x   1 root       sys             18 Jan  8 16:34 /usr/bin/perl -> /opt/perl/bin/perl
bash-4.4$ ll /opt/perl/bin/perl
lrwxrwxrwx   1 bin        bin             14 Jan  8 16:45 /opt/perl/bin/perl -> ./perl-dynamic

Is this a magical perl binary which decides which version and architecture to use?

$ perl -V
Will show you the details.

Both perl-static and perl-dynamic are built with the same configuration (at least for what I can see on my HP-UX 11.31) and both are built with -Dusedl

perl-static is linked with libperl.a (or linked with all .o files), whereas perl-dynamic is linked using libperl.so. You can check the differences with ldd perl-static and ldd perl-dynamic.

There is no functional difference
