Hmm, for future proofing, it might be interesting to use a base/factory class like Sys::Exporter that then either automatically or manually selects the correct backend like Sys::Exporter::Linux and stuff. That way, it could also support cross-platform builds.

use Sys::Exporter;

# Automatic detection/configuration
my $exporter = Sys::Exporter->new();

# Prepare a cross-platform export
my $exporter = Sys::Exporter->new(
                        OS => 'FreeBSD',
                        rootdir => '/mnt/freebsd',
                        libtools => '/home/nerdvana/crossplatformldd',
               );

I'm not specific about a name, but putting the OS as the last element of the name instead the first makes sense to me.
