eMBR_chi has asked for the wisdom of the Perl Monks concerning the following question:

Dear Wise monks,
I need some help with installing and running graphviz on my linux box. My distribution is CentOS 5. I installed graphviz via 'yum install*'. That was successful. But I have not been unable to run my perl scripts off it. This is usually the error report I get:

Can't locate graphviz.pm in @INC (@INC contains: /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.8.8/i386-linux-thread-multi /usr/lib/perl5/5.8.8 .) at trygraph.pl line 6.

I find that I am also unable to locate graphviz.pm. I have also installed the perl-GraphViz module, even though I thought it was contained in the initial installation. But it has been unsuccessful. I suppose there is something that I have not yet got quite right and would be happy if anyone can point me in the right direction. Thanks

    Such things are case sensitive, you seem to have use graphviz; when you should have use GraphViz;.

    Can't locate graphviz.pm in @INC
    Could it be as simple as using the proper case? Perl is case-sensitive, as the GraphViz SYNOPSIS shows: 
    use GraphViz;

    I find that I am also unable to locate graphviz.pm.
    This script can be used to locate all .pm files in your @INC directories. It uses regular expressions, so you don't have to know the exact name or case: 
    findpm -p graphviz

      Thank you so very much. Your post was very useful. It also turned out that I had used the wrong case. Once more thanks.
