You are using the one in your overlay here. i have this:
...
#ACCEPT_KEYWORDS="~x86" emerge emelfm2 -pv

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild  N    ] app-misc/emelfm2-0.0.9-r1  +nls 456 kB

Total size of downloads: 456 kB

Think it's better they use "virtual/fam" or some sort of
virtual/a-name-here. Gamin ebuild already provides "virtual/fam".

They already DEPEND on virtual/fam.
It's just a matter of naming IMO, the name "fam" (File Alternating
Monitor IIRC) merely coincides with fam in "virtual/fam", not like
"virtual/mda" which is clearer.
