Some other things to try after @system if the problem persists:

Check the ownership and access rights of /etc/group:

$ stat /etc/group
  File: /etc/group
  Size: 855       	Blocks: 8          IO Block: 4096   regular file
Device: 80ah/2058d	Inode: 1055521     Links: 1
Access: (0644/-rw-r--r--)  Uid: (    0/    root)   Gid: (    0/    root)

Check the particular group ID:

$ grep :7: /etc/group
lp:x:7:lp


Emerge cups which installs lp:

emerge -1aDv net-print/cups

Then try again as suggested:

emerge -1aDv acct-group/lp
