Here is the output:

root@fireball / # emerge -pv --depclean blas-reference

Calculating dependencies... done!
   sci-libs/blas-reference-20070226 pulled in by:
     virtual/blas-1.0

 >>> No packages selected for removal by depclean

root@fireball / #

Two things.  I read about this on -dev but didn't realize it was going 
to affect me until I saw the message.  After I added fortran to my USE 
line in make.conf, it only rebuilt gcc then revdep-rebuild rebuilt 
dev-lang/ifc-10.0.026-r1.  Everything appears to be clean now.

To think people wonder why my USE line is so big.  I keep having to add 
stuff when portage pukes but portage never tells me when one has fell 
off the reservation and needs to be removed. < sighs >  Over the years, 
it adds up.
