Right, but if you are mixing major versions of perl, you'll probably encounter issues in other places. mod_perl may be the first place you are seeing this. Think of it this way - would you try this same install procedure with 5.6 and 5.8? Maybe 5.8 and 5.10 work together seamlessly, but I would look to that as a likely source of problems. ack is App::Ack, available from CPAN. I've pulled down 5.10.1 but haven't had time to do a build yet. When I do, I'm going to install 5.10.1 a separate location from my 5.8 libraries. Maybe it can integrate with 5.8 (the perl 5 porters are a very talented crew), but discovering an edge case is not something on my todo list :) I like to keep my mod_perl setup using a different perl build than the system perl. That way, I won't hose my system if I want to try some new build options for my mod_perl based perl install. > It is hard for me to imagine that the fact that I gave the perl > build process a list of directories to append to @INC should > affect the presence or absence of a symbol in the resultant perl > binary.
