[Exim] @INC problem with exim.pl

Hi folks,

I'm trying to add a new function to my exim.pl, but I get the
following error in exim_mainlog:

> 2004-03-03 13:56:19 1AyTsn-0006ZG-AG failed to expand condition

> /usr/lib/perl5/5.6.1) at /usr/lib/perl5/5.6.1/lib.pm line 4.
> BEGIN failed--compilation aborted at cm line 4.

Now I can do perl -e 'use Config;' from the command line with no
output or errors.

Adding use strict; and use warnings; I can do
    perl -c filewithjustmycode.pl
and
   perl -c allthecodetogether.pl
and the code is error free.

A few other tests pass (Perl's compiled @INC looks right, an INC_TEST
script checked out ok, etc.

Tech support says:

I got this bit directly off a greylisting website, I put it at the
very top of my check_recipient ACL... perhaps it should go elsewhere?

require domains = +local_domains : +relay_domains
            condition = ${perl{greylist}}
