    <p>Here is my problem. I am running OS&nbsp;X&nbsp;v10.7 (Lion) and want to set up an old Perl program I have written (was then using a Windows System with <a href="https://en.wikipedia.org/wiki/ActivePerl" rel="nofollow">ActivePerl</a> and then its ppm).</p> <p>I read to use CPAN to install Perl modules (I am trying to install the Graph module). Whenever I tried to install it, it failed from a refused connection. Why? So I read that I should run the following to update CPAN and fix any broken links:</p> <pre><code>cpan&gt; install Bundle:CPAN cpan&gt; reload cpan cpan&gt; index cpan cpan&gt; exit </code></pre> <p>However, after doing this I am stuck with this every time I try to do a CPAN install or upgrade:</p> <pre><code>New CPAN.pm version (v1.9800) available. [Currently running version is v1.9456] You might want to try install CPAN reload cpan to both upgrade CPAN.pm and run the new version without leaving the current session. </code></pre> <p>I was trying to use the default Perl stuff that is included in OS&nbsp;X rather than downloading ActivePerl. How do I fix CPAN and install the Graph Module?</p> <p>PS: Running install CPAN and reload CPAN didn't do anything, but it generated the same message.</p> <p><strong>UPDATE</strong> I was able to upgrade to v1.9800 doing a manual install (make, install) through the terminal. But I am still unable to install the Graph Module. Here is what I am getting:</p> <p><a href="http://cloud.jjnford.com/3D1C1H4217222b1p1O3a" rel="nofollow">http://cloud.jjnford.com/3D1C1H4217222b1p1O3a</a></p> <p><strong>UPDATE - PROBLEM SOLVED</strong> I was finally able to solve the problem. I just moved the /User/jj/.cpan directory to User/jj/.cpan_bak and then reconfigured CPAN and the Graph Module installed with no fuss. </p>

    1. COWhich version of Perl are you using? Are you updating the system-provided Perl, or one of your own building?

    2. CO@Jonahan I am using the system-provided version of Perl. I was able to solve the problem by doing a manual CPAN install and reconfiguring it. Probably just and issue with the older version and Lion. Thanks for your interest though.

    3. COBe cautious about changing the system installation. I haven't specifically heard of a Perl module upgrade breaking things, but I long ago decided that it was safer to leave the system Perl well alone, and to only modify the modules in versions of Perl built by me and installed separately from the system Perl. Maybe that's (ouch!) 15-year old paranoia. But I either use the system Perl unchanged or use my 'home-built' Perl; I don't risk modifying the system Perl.

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
