Perl 5.10.1 have been release. You can download it from the CPAN, or if you can’t wait, here.
Next, you need to build it:
mkdir ~/perl/5.10.1
cd ~/code/build/perl-5.10.1
perl Configure -de -Dprefix=${HOME}/perl/5.10.1/
make
make test
make install
Add the path to your environment
export PATH=${HOME}/perl/5.10.1/bin:$PATH
and install your CPAN’s modules:
PERL_MM_USE_DEFAULT=1 cpan Bundle::CPANxxl Task::Kensho
Now you can start to play with it :)
