I just wanted to add a note.
of all the OSen I've used, the one most renowned for freeing the user of "DLL
hell" effects is AIX. I gather this is in part because SMIT (the package
manager) is such a draconian beast, and in part because the binary
compatability management for libraries is extremely thorouh. No small
coincidence that this comes from this little company, IBM, with pots of cash
to pay developers to maintain ridiculous number of library dependency and
vesioning branches throughout IBM's very generous support cycle. Look at the
APAR/FIX log for any AIX C package, and you will be left in mesmerized awe.
The problem is that so few OSS projects have such manpower. Of course, I
don't know what Microsoft's excuse is ;-). Anyway, I believe that you can
only ever get 2 of the following:
1) A package in active development
2) Freedom from DLL hell
3) Nice modularity for integration with other subsystems (i.e. APIs of broadly
Unless you have IBM-type bucks. Pick two, if you're lucky. You're not going
to get all 3. I think PyXML offers 1 & 3. Anyone who is not satisfied with
that should submit IBM-type bucks to .... Well, once we know there are any
takers, we'll figure out an address, to be sure ;-)
