In -Dprefix=$HOME/localperl, the variable $HOME is what you're not getting,
I think. That configuration line means "build a new installation of Perl in
my home directory and put it all into a folder called localperl."
(Normally, the build would get put into the directory you choose, but then
into bin/, lib, share/ and man/ directories there.)

Apparently, you were logged in as root when you built and installed this
version of Perl. That was a mistake. You should be root as little as
possible. (I can tell you were root since $HOME for root = /root. You
configured it to be built in $HOME/localperl and it was.)
In any case, I would recommend that you remove entirely the localperl/
directory in your root home directory, and then start again. Download the
latest sources as a regular user, in your regular user's $HOME. Then build
it and install it there. After that you should be able to invoke it with
this shebang line:
#!/home/username/localperl/bin/perl
Hope this helps, T
