We use Debian-style naming for perl recipes in OE. Looking over the perl support recipes in meta-security I think at least one of them needs fixing to match this i.e. curses-perl probably needs to be named libcurses-perl. Additionally env-perl has been added there, but it looks to me as if this is a duplicate of libenv-perl which is in OE-Core already. Someone more familiar with perl needs to look at these to confirm, preferably before the 1.5 release since these are new recipes and these should be very simple fixes.
