Technically, you don't actually need to recompile something that's pure
perl, or that only requires perl to run some scripts.  However
everything that has a binary interface with perl -- XS modules, software
with embedded perl interpreters -- certainly will need recompiling to
match the new threaded ABI that has now become the default.

The advice to 'recompile everything that depends on perl' is overkill,
but it's a simple way to be sure that you have in fact recompiled
everything necessary.  Picking out only those ports that really needed
to be recompiled would require a procedure too unweildy to be usefully
described in UPDATING.

	Cheers,
