Hi Casandra,
(Wayne already answered this much more succinctly than me, but here is my
answer anyway.)
I think you're almost there.
The fact that you get no error message when you type
perl -e "use Bio::SeqIO;"
in the directory src/bioperl-live/ tells me that probably Perl doesn't
"see" where you put BioPerl. That's what the PERL5LIB variable does; it
tells Perl that it should look for Perl modules in the directories named in
the environmental variable PERL5LIB.
If you type
printenv PERL5LIB
do you see
/Users/mcasandrariera/src/bioperl-live
?
If not, then redo steps 5-10 and then try typing
printenv PERL5LIB
again. Make sure that in step 8, instead of
export PERL5LIB=/Users/dave/src/bioperl-live
you type
export PERL5LIB=/Users/mcasandrariera/src/bioperl-live
To answer your other questions:
although I don't know what src means...
src is just a directory name. It's short for "source", which itself is
really short for "source code". src the name of the directory where I keep
all of my source code libraries like BioPerl.
Maybe it will be useless to explain it to me, but, why this method isn't

The short answer is that by following the zero-install instructions, you
won't be able use some parts of BioPerl (which I'm betting you won't need
right away).
Chris and Scott's advice is correct and the right way to go in the long
run. Once you've gotten your feet wet a bit and become more familiar with
Perl and BioPerl, you may want to come back to their approach and try it
again.
Best,
Dave
