If the package was written for 2.x and "the latest version of Python"
means 3.X, this is not surprising; your options are (1) wait until the
package maintainer releases a 3.x-compatible version (2) port it to
3.x yourself (3) use 2.6

Otherwise: What does "will not install" mean? Are these pure Python
packages or do they include C extensions (binary (pyd) or source?)? At
what stage of the installation does the installation fail? With what
error message(s)? With what versions of Python?
