It depends entirely on how exactly you're using Perl, and how Apache is
configured. If you're using mod_perl2 then you would have to recompile
mod_perl2 to point to the new installation.

Using mod_perl is not really recommended unless you specifically need to
tie into Apache's request chain; that in itself is not common. A more
preferred configuration is FastCGI, or a dedicated application server.
With FastCGI you would only need to change the shebang line in the Perl
script to point to your local version of perl. This would also require
rewriting the Perl script to use the FastCGI module, and to do so in a
manner that works, so it may not be a viable alternative.

In other words, it's hard to give you a firm answer without knowing more
about your configuration. Showing us your Apache configuration would
provide the best answers. Knowing how the webapp is written would also
help.
