Portversion claims a newer port is available but it ain't so

[Clint Olsen]

# portversion flac
[Updating the pkgdb <format:bdb1_btree> in /var/db/pkg ... - 312 packages found (-1 +1) (...). done]
flac                        <
# portupgrade flac
#
# portversion -v flac
flac-1.1.0_3                <  needs updating (port has 1.1.0_4)

This is not the first time I've seen this.  There's a port called 'gail'
out there that I can't upgrade either.
