[Bioperl-l] parsing a phyloxml file

[Chris Fields]

Also, the phyloxml regression tests should at least indicate a problem  
with the module.  If they are passing then there is another problem at  
hand, either with the tests skipping based on a bad module (should  
fail) or .

 From the base directory of a BioPerl core (either main trunk or 1.6):

./Build test --test-files t/Tree/TreeIO/phyloxml.t --verbose
