title: How can I install or upgrade a CPAN module that is in the latest Perl, without installing the new Perl?
body: <p>I'd like to install a Perl module (in this case, <a href="http://search.cpan.org/search?module=FindBin" rel="nofollow noreferrer">FindBin</a>), but since it is included in the <a href="http://search.cpan.org/~dapm/perl-5.10.1/" rel="nofollow noreferrer">Perl 5.10.1 distribution</a>, <code>cpan</code> wants to install Perl 5.10 for me.  Is there a way of installing just the module via <code>cpan</code>?</p>
  
  <p>The only option that I can see is <a href="http://search.cpan.org/src/TTY/kurila-1.19_0/lib/FindBin.pm" rel="nofollow noreferrer">installing directly from source</a>, which seems a bit crude as there is no separate package (for example, <code>Makefile.PL</code>, etc.), just the bare <code>.pm</code> file.</p>
  
  <p>Since this is a small module that only has the one file, it's doable in this case, but what if I wanted to install a much larger package?</p>
  
  <p>EDIT: This is somewhat aside from the original question, but speaks to the general issue of modules being packaged up with Perl distributions: I discovered that the "standalone" FindBin (<a href="http://search.cpan.org/src/TTY/kurila-1.19_0/lib/FindBin.pm" rel="nofollow noreferrer">version 1.49</a>) had a syntactic error, so I retrieved <a href="http://search.cpan.org/~dapm/perl-5.10.1/lib/FindBin.pm" rel="nofollow noreferrer">version 1.50</a> out of the Perl 5.10.1 distribution... However since the module is now listed on CPAN as part of Perl 5.10, I am unable to find the CHANGES file describing what was changed/fixed in this delta. Is it reasonable that I should have to go into the developer repository to pull out this information?)</p>

  <p><strong>EDIT 2. Okay, here's a better example</strong>.  On Perl 5.8.8 I have version 1.04 of Carp. However, I see that Perl 5.10.1 comes packaged with version 1.11. Is there a way of getting CPAN to install the latest version of Carp for me without dragging in all of Perl 5.10.1? I can't even find a link to the Carp module on CPAN except to the <a href="http://search.cpan.org/~dapm/perl-5.10.1/" rel="nofollow noreferrer">perl 5.10.1 installation</a>.</p>
