I don't know how well known this is (it's probably quite old new for you) but recently I had the problem of wanting to run a Perl-script on a non-rooted Android-tablet and came across the fabulous Termux-project.

Installing this app gives you a terminal-environment and with a simple

pkg install perl

you get a working 5.26.1 perl. Now add

pkg install make
pgk install clang
[download]

and voila you have a fully functional cpan-client that allows you to install even xs-modules.

Really nice...
