Your Perl modules won't be deleted unless you use the "clean install"  
option, which deletes *everything*.

/Library/Perl/5.8.1 & /Library/Perl/5.8.1/darwin-yadda is included in  
@INC by default. So far as Perl itself is concerned, 5.8.6 (which is  
what Tiger ships with) is binary-compatible with modules built for  
5.8.1.

Note that there's no guarantee that *every* module will work  
perfectly, just that the interface between Perl and its modules  
hasn't changed. If you have a Perl module that's a wrapper for  
libFoo, there's also the question of whether the binary interface to  
libFoo has changed or not. If it has, you'd need to rebuild that  
module against the newer libFoo.
