Comment:

 I reenabled perl in pidgin and finch in r68115. I didn't see a reason to
 add a no_perl variant. (Or is there a reason why a user would want to
 disable perl support? It's not as if doing so would save them from having
 to install perl, since perl is already an indirect dependency.)

 I also added an fs-traverse block to delete the perllocal.pod file that
 then got created. No port should create or claim ownership of this file.
