35 I suppose you got the idea by now ;-) Do you need dev-lang/R? If not,
36 then "emerge -pv --depclean dev-lang/R". Do you need the package(s)
37 that this brings up? If not, continue --depclean those until you reach
38 something that has no other dependencies; meaning you reached the top
39 level. Do you need *that*? If not, unmerge it, then depclean
40 everything (just "emerge -a --depclean".)

42 This should get rid of all stuff you don't actually need/want.

56 GCC is a compiler collection. You usually only need gcc and g++.
57 Fortan, Objective-C, Objective-C++, ADA, Pascal, Java, whatever else is
58 usually something you don't install unless you know you need it.
