setting ENV howto?

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

I am trying to install some modules from cpan but they need some ENV vars set. the error says
'The simplest method is to use the standard "DBI_DSN" environment variable to define a DBI connection string.'

I thought I would put them in my .tcshrc file so I added 

setenv DBI_DSN dbi:Pg:dbname=template1
setenv DBI_USER auser
setenv DBI_PASS apass

[download]

but it didn't work... so how do I set them so the modules will install. When I installed DBD::Pg I hardcoded them but that is just a hack... I want to know the real way this should be done.

    I assume you 
    source .tcshrc

    [download]
    after making the change and before installing?

    Otherwise, I'd suggest posting the error message.

        You haven't commented on whether you understand what source does.
