I have upgraded to the new CLD-14 edition & I noticed when using "emerge -ca" after last upgrade that it has many pkgs it wants to delete & most of them are perl related.I dont recall seeing a list like this & am wondering if its because Perl was upgraded as it seems strange that my system would need to remove so many perl pkgs all of a sudden & are module related as well & would appreciate any insight into wether its OK or not.
Would it be better to run Perl-Cleaner, I want to look to see if there are pkgs that have replaced them before deleting etc...

Would you like to unmerge these packages? [Yes/No]

I really was so close to following what emerge -ca wanted to do until I was reminded about perl-cleaner,& the reason I nearly did that was because I did not see any message from emerge about perl being upgraded.I also chose to follow what perl-cleaner advised after it complained about blockages & unmasking & it fixed up 40+ pkgs But now I have found emerge -ca still wants to delete a heap of perl pkgs still.
Does anyone know if I should remove all these pkgs.Would appreceate insight as they do not seem to be duplicates.
