Installing Perl module in Unix

Installing Perl module in Unix

This is my first time installing a Perl module and Im having some trouble.
Im trying to install manually In unix. These are the steps I am following
(Installing DBI module in this case)
Download DBI-1.628.tar.gz tar file,
Uncompress file with $ tar -zxvf DBI-1.628.tar.gz
So far no problems, Its the next step that is confusing me... It every
tutorial Ive seen so far Im told to locate Makefile.PL then run the
following commands...
$ perl Makefile.PL
$ make
$ make test
$ make install
In my case ,after locating Makefile.PL and running
$ perl Makefile.PL
...some output follows. I get these messages 'Checking if your kit is
complete... Looks good' & 'Writing Makefile for DBI'
Then Im back in my user command prompt. Note I still haven't entered these
commands
$ make
$ make test
$ make install
From the command prompt if I enter the make command now I get a -bash:
make: command not found error.
Im an absolute beginner at this so please excuse me If I am missing
something rudimentary. Thanks in advance for any help.
