 I should note that a specific snapshot of the headers may be preferred
 to head, to ease maintenance.  You may also wish to add some specific
 provisions for the "makesum" target.
 
 This problem is occurring with lang/gcc44 from Ports, when
 devel/binutils is installed, because then the latest gcc44 snapshots
 are automatically preferring devel/binutils to the base system
 binutils.  This is a bug in the lang/gcc44 port, and it should be
 explicitly instructed to use one or the other (either hardcoded, or
 based upon an OPTION), as lang/gcc45 is now wired to devel/binutils.
 I have cc'ed the gcc maintainer.
