If they wanted to install two incompatible versions at once, they'd just
stick them in different directory trees (ie, not both /usr/lib64/perl5).
Given the amount of stuff in a Perl distribution besides libperl.so
itself, I should think some such thing would be necessary regardless.
(Or, if you prefer, the thing that is binding /usr/bin/perl to its
correct library is an RPATH setting, not a soname version number.)
