We have some Perl software called nexplot that we developed for our own 
purposes
that may be of use.  It is not a part of BioPerl, yet.  You can test 
out the functionality
at www.molevol.org/nexplorer, and from there you can download the Perl 
library
and applications to make PostScript plots of trees.  Nexplot uses a 
NEXUS files as
input, and outputs a tree with the tips aligned with a data matrix 
(e.g., a sequence
alignment).  However, it has a tree-only mode, and the NEXUS input file 
incorporates
the Newick standard tree format in its TREES block, so it would
be easy (in principle) for you to just create NEXUS files with the 
trees you
want to display, and then use nexplot to display them  (you can even put
multiple named trees in a single file, and nexplot can plot a tree 
chosen
by name).
