I'm fairly new to Macports so please forgive me if this is an 'dumb' question. I am trying to build gtk-sharp, which uses avahi which, in turn, uses py-gdbm. For various reasons, I have both python2.4 and python2.5 installed (both installed as dependencies for other packages - I have no knowledge of python and have not installed either from 'choice'). When configuring avahi, it could not find py-gdbm although the 'ports installed' command listed it as active. It turns out that the python 'sys.path' command includes all of the pythin2.5 directories, but the py-gdbm package installs into the python2.4 directories. I have subsequently changed the avahi dependency from 'py-gdbm' to 'py25-gdbm' and it has installed correctly. However I don't think that this should be the sort of thing that I should be 'playing' with. What is the correct process that I should be using to handle this situation? It would appear that the python packages are tied to a specific version and are not generic. Is this right? Thanks Susan
