Bugzilla Bug 208485

After running revdep-rebuild with the "-i and -e" options, I obtained the
following list of packages and error:

 * All prepared. Starting rebuild
emerge --oneshot  =!!! =All =ebuilds =that =could =satisfy
="=sys-fs/captive-1.1.7" =have =been =masked. =!!! =One =of =the =f

!!! '=!!!' is not a valid package atom.

I guess I should mention that this occurred after I did " emerge -Du world",
after not having done so in a year. Not sure what else could help you guys out.

Reproducible: Didn't try

Actual Results:  
emerge -Du world
revdep-rebuild -i -e

Expected Results:  
 * All prepared. Starting rebuild
emerge --oneshot  =!!! =All =ebuilds =that =could =satisfy
="=sys-fs/captive-1.1.7" =have =been =masked. =!!! =One =of =the =f

updated the necessary packages

This is gentoolkit and not portage bug.
