Advice on migrating modperl from NT to Linux ?

[Rod Butcher]

I am looking to migrate a small modperl-based webhosting and ISP service
from NT to some flavour of Linux. Are any particularly modperl-friendly or
unfriendly or are they all much the same ? I'm fairly comfortable with
Redhat, but I hear stories of packages being broken.
Any feedback or pointers to discussions, articles etc would be much
appreciated.
Thanks
Rod
