Installing a CPAN Perl module from a non-root account

Problem: you do not have root permission but want to install a Perl module in a local directory and the module can be located from your scripts.

CPAN Perl modules

Refer to Installing CPAN Modules and this section in the CPAN FAQ.

Download the Perl module

Find the Perl module you want. Google or the CPAN Search Site are usually good ways to find the module. Download a copy of the entire package (usually a .tar.gz, not the individual .pm "Perl module" file) into a download directory. I usually keep a directory named ~/downloads.

Install the Perl module into your ~/lib directory

Unpack the CPAN Perl module:

cd ~/src

tar -zxvf ~/downloads/Statistics-Descriptive-2.6.tar.gz

(The conventional installation method is:

cd
~/src/Statistics-Descriptive-2.6

perl Makefile.PL

make

make test

make install

)

But specify the installation into ~/lib/perl5 instead:

cd
~/src/Statistics-Descriptive-2.6

perl Makefile.PL PREFIX=~/lib/perl5

make

make test

make install

Installing
/home/you/lib/perl5/site_perl/5.8.2/Statistics/Descriptive.pm

Writing
/home/you/lib/perl5/site_perl/5.8.2/cygwin-thread-multi-64int/auto/Statistics/Descriptive/.packlist

Appending installation info to
/home/you/lib/perl5/5.8.2/cygwin-thread-multi-64int/perllocal.pod

Change your Perl scripts so that they can find the Perl module that you have installed locally

See this section in the CPAN FAQ.

I prefer the first method that is mentioned, which is to set the environment variable. This is easy to do in a login script.

setenv PERL5LIB /path/to/module sets the environment variable PERL5LIB.

With Bash:

export
PERL5LIB=~/lib/perl5/site_perl

Remove the Perl module

Just remove the appropriate files from ~/lib/perl5. Or use the ExtUtils package to help you remove the files.

Google AdWords Keyword Tool

NetSmarter @ 2008-05-30 00:01 (Tools and Books)

I haven't used Google's AdWords Keyword Tool that much, mainly because I'm not an active AdWord user. However, I just learned that this tool can help to know what Google thinks your website is about. Below is the URL of that tool:

https://adwords.google.com/select/KeywordToolExternal

With this tool, you can type in the URL of your web page and click on "Get keyword ideas". The result is what Google's LSI (latent semantic indexing) spider thinks your page is about. It's also telling you the kind of AdSense ads that it is likely to place there.
