I'd like to point out that there are other solutions besides what planet
adopted and DLL Hell.  For example, as Carl suggested in his first
message, the system could keep separate copies of the library for each
package that required it.  

This is the solution proposed by the group I've worked with at Sun for
Fortress [1], and it's also the system that you get with units in
mzscheme.
