Right, it took ~8 yrs to go from 5.8 to 5.10.  I'd like to point out that Python users are in the same boat: the
Python version for CentOS 5 is 2.4.3, and Biopython requires a minimum of python 2.5 (and recommends
python 2.7).  

We can always state that perl 5.8 is supported for the upcoming Bioperl release, but we're dropping v5.8
support for any future releases.
