[Bioperl-l] parsing a phyloxml file

Hi,

I am trying to parse a phyloxml file but I get the message error below:

Bio::TreeIO: phyloxml cannot be found
Exception

For more information about the TreeIO system please see the TreeIO docs.
This includes ways of checking for formats at compile time, not run time
Can't call method "next_tree" on an undefined value at parse.pl line 1.


Does anyone can help me?

Thanks a lot,
