The barbs in my game always build the collossos, usually because i forget to build a forge
check this out ... the new vanilla SGOTM that looks really really fun!
the stuff i know officially about what barbs can and cannot build, is in Assets/XML/Civilizations/Civ4CivilizationInfos.xml . there's a different one for Warlords/Assets/etc.
that's a text file. you can open/edit it with notepad, doesn't need anything fancy. all the civs are listed in there, barbarians are last. the barbs are the only guys with long lists like in this spoiler box. the lists are much longer, i just pulled out some samples. like RockNRoll, had to list it because i would giggle so much if they built it. i mean have you heard their civ music when you check out one of their cities?

as far as i can tell, every "NONE" on those lists means barbs aren't ever allowed to make that unit or building. so my guess is that is you took a section out, say from <building> to </building> for library, then they'd be able to build libraries after they learn writing. that's only a guess, copy files before altering them, move to custom assets, use adult supervision, poster is not responsible if your pc explodes.
Edit: Oh and as for the file in question, I could not find it in either Vanillia CIV4 Assets or Warlords.
OMG, can you imagine the Barbs with ICBMs? That would be scary
hmmz. i don't know what to tell you, that's exactly where mine is. it's not where my own games that i play are saved, it's where the game itself is installed. so for me, it's in the I:/civ4/Assets/XML/Civilizations folder and then there are 4 files in there. hopefully it's something easy like that, you're looking where the saves go and not where you installed it? cuz it's fun to peek .
