Since you're not a native Perl programmer have you tried looking at our REST API? We have two endpoints which may be of interest to you:
The first provides access to the GeneTrees in both Newick & PhyloXML; the later of the two also returning the protein/cds sequence of each member in the tree optionally aligned. The second endpoint gives you orthologs which is where, as Miguel pointed out, dnds is held. So to use your example (using PROCR):
Would give you the PhyloXML tree & nh trees. However we've used some prior knowledge that PROCR is in this GeneTree (this is a feature we will extend to asking for GeneTrees by their Gene).
Then to get the homologies for this gene (which can be restricted with other parameters):
Of course the REST API is a beta product so it may not provide enough information at the moment but please let us know how we can improve it.
