[ubuntu-uk] Help with perl

[Gareth France]

I posted about choosing a new laptop recently and have settled on a 
machine, set it up and I'm just getting settled in. I use a perl script 
for work and have discovered it doesn't work any more. It is asking for 
the Text/CSV.pm module which I have installed. However it still produces 
the following error when run:

Can't locate Text/CSV.pm in @INC (you may need to install the Text::CSV 
module) (@INC contains: /etc/perl 
/usr/local/lib/x86_64-linux-gnu/perl/5.20.1 /usr/local/share/perl/5.20.1 
/usr/lib/x86_64-linux-gnu/perl5/5.20 /usr/share/perl5 
/usr/lib/x86_64-linux-gnu/perl/5.20 /usr/share/perl/5.20 
/usr/local/lib/site_perl .) at kt74 parse line 4.

I have located the file in question and copied it to every one of these 
locations however I've had no luck. Is there anyone out there who can 
point me in the direction of a solution? It's driving me mad now!

Thanks
Gareth
