gcc 4.8.5 doesn't match >=4.8?

[John Klos <john%ziaspace.com@localhost>]

Installing sysutils/xentools48 on netbsd-7 from today:

===> su-do-clean [pciutils-3.5.5 xentools48-4.8.0nb1] ===> Cleaning for pciutils-3.5.5
=> Returning to build of xentools48-4.8.0nb1
=> Build dependency gcc48>=4.8: NOT found
=> Verifying update for ../../lang/gcc48

cc --version
cc (nb2 20150115) 4.8.5

Huh?
