how-to build a multithreaded perl from source as a non-root account

echo doc ensure you are logged in as the pmuser
cd ~ ; mkdir -p ~/.perl/

echo doc used the following url to download the source : http://www.cpan.org/src/README.html

echo doc dowload the latest perl source code
wget http://www.cpan.org/src/5.0/perl-5.18.0.tar.gz

echo doc uppack it
tar -xzf perl-5.18.0.tar.gz

echo doc go to the unpacked dir
cd perl-5.18.0

echo configure the builder script to build thread supporting perl binary
./Configure -Dusethreads -des -Dprefix=/<<a_home_dir>>/.perl/

echo doc run make
make

echo doc run make test
make test

echo doc run make install
make install

echo check that the perl IS NOT in the path
-bash-4.1$ which perl
/usr/bin/perl

echo doc now the pmuser has it's own fully fletched perl binary , which is different from the `hostname -s` 's own perl binary and does not break anything on the <<a_home_dir>> installation , sinche we will not vchang e the host dependant settings ...

echo doc but in order to be able to use it you would have to add the following to your calling shell:
export PATH=/<<a_home_dir>>/.perl/bin/:/<<a_home_dir>>/.perl/perl-5.18.0/:$PATH

echo doc now check once again
which perl
which cpan
