No, there's no way to install a port without its dependencies.  
Instead the ports should be fixed so they have the dependencies you  
want.

py-ipython, py-beautifulsoup and py-psycopg2 require python24 because  
that is what ports whose names begin with "py-" do. Ports that depend  
on python25 have names that begin with "py25-". It was decided some  
time ago that since Python 2.4 and Python 2.5 are so different, there  
must be separate ports for Python 2.4 and Python 2.5 versions of each  
other port. Someone with knowledge of Python (which would not be me)  
would have to make copies of those ports and call them py25-ipython,  
py25-beautifulsoup and py25-psycopg2 and fix them up so that they  
work with Python 2.5.

Only py-psycopg2 seems to require PostgreSQL. The port is maintained  
by Landon Fuller. You could ask him if it is possible to provide a  
postgresql82 variant for that port.
