Hi Mark,
let me try to tackle your questions incrementally.

Did you put them into their own package or also into their own module? I hope
you know there's a difference. Do the module and package share the same name.

By "EXPORTER" you probably mean «use parent 'Exporter';» (or use base
'Exporter') along with the special variable of @EXPORT, @EXPORT_OK, etc. In any
case, is it a module that does not have a "package" specifier (in which case
it will dump its contents into the current package). Maybe it does have a
"package" specifier, but names from it are called using MyPackage::my_sub()
(i.e: fully-qualified names).

Use of Exporter.pm (or Sub::Exporter for that matter) is optional, and you may
opt to avoid them if you're creating an object-oriented interface.

Can you give a code sample that reproduces the issue?
