Do you actually need a relocatable perl, or do you simply want to install Perl somewhere other than the default?

On a Linux box (which you appear to be using), the latter is trivial using perlbrew, or even manually.

curl -L http://search.cpan.org/CPAN/authors/id/S/SH/SHAY/perl-5.20.1.t
+ar.gz | tar xz
cd perl-5.20.1
. Configure -des -Dusethreads -Dprefix="$HOME/perl"
make
make test
make install
