I never noticed the trailing ":4" before and I have no idea what it
means. I
searched the gentoo website but haven't been able to find anything

Does anyone what it is about?
It's the value of SLOT. There are package for which multiple versions
can be installed
at the same time, e.g. on my system
eix sys-devel/gcc shows
Available versions:
(2.95) (*)2.95.3-r9 (~*)2.95.3-r10^s
(3.1) (*)3.1.1-r2

=========^^^ SLOT value.
So, if you want to (re-)emerge the 4.6 version of gcc, you use
emerge -v1 sys-devel/gcc:4.6
(Just using emerge -v1 sys-devel/gcc would (re-)emerge the version with
the highest slot value,
4.7 in this case.)
