The specifics of perl have been addressed, but it's worth noting that
sometimes, you do. A good example is tk; it's perfectly possible to have
multiple versions of it installed because they're installed to different
paths and have different names in /usr/bin, and sometimes necessary,
because programs that run under one version(say, requires wish8.3) might
not work under a later version(wish8.4). If the program isn't
specifically referring to a version, it might need to be told which
version to use; and in this case, i.e. if a program starts with #!
/usr/bin/wish, the versionless command will just advise you to use one
with a version.
Generally, if an interpreter has two versions in the /same/ ports tree,
there's a reason for it. You just might not have any software installed
that requires the different versions. Software besides interpreters
might have different versions in there for a different reason, and they
might not get along, which you'll be told if you try to install
both(either directly or as the result of installing something else).
