Thanks haukex - that's extremely helpful.

or, in the worst case, you're not using strict.

The main script has use strict; but it seems that does then apply to the module it calls...I know that now!

So now I've added use strict; I get a whole bunch of Global symbol requires explicit package name errors even though they all have my or our declarations. I tracked this down to the declaration happening later in the module than methods that are throwing the error.

It also highlighted another error with this: 

$db =~ s/_.+?_/_$dbname_/;

The variable $dbname is declared but in the regexp it is looking for $dbname_. I have solved this for now with: 
my $temp = "_$dbname"."_";
$db =~ s/_.+?_/$temp/;

But - I feel sure there is a more elegant way!
