perl-Unicode-String is not available in EPEL.
Please branch the package accordingly for EL-5 and optionally for EL-4.
If you're short on time, not interested or simply need help maintaining it in
EPEL I'd be glad to (co-)maintain the EPEL Branch with/for you.
Package Change Request
Package Name: perl-Unicode-String
New Branches: EL-4 EL-5
Updated EPEL Owners: pghmcfc, ixs
Given the time this has been open without reply,
I will just go ahead and make the requested branches.
Aurelien: If you decide you would like to maintain in EPEL, just let us know.
This is now branched, built, and released to the testing repos for EPEL 4 and 5.
Andreas and I are set up as co-maintainers for the EPEL branches.
