Here is an example of installing from source using the defaults. If you want to modify the defaults, have a look at the INSTALL document.
$ wget https://www.cpan.org/src/5.0/perl-5.26.3.tar.bz2
$ bunzip2 perl-5.26.3.tar.bz2
$ tar xvf perl-5.26.3.tar
$ cd perl-5.26.3
$ sh Configure -de -Dprefix='/some/dir' # Where to install
$ make
$ make test
$ make install
Then edit the PATH environment variable to include /some/dir/bin
such that the shell can find the new perl.
