How easy this is to do depends on how much that package you are replacing will change with the upgrade. Assuming that the package is not a dependant of another package, you can remove the debian version and use 'alien' to install the tgz version. HOWEVER, perl is not such a package. The unstable distribution of debian has been flopping around like a fish on a pier for a short time now, because of the introduction of perl 5.005. A large number of debian's scripts and installation system use perl, and break when you upgrade. Once the devel people have everything figured out, it will be fairly easy to upgrade. Carl
