as a start you could try the distribution from the garden; at least it's 
a good way to figure out if there is something fishy with your system

there are fundamental differences between tl 2012 and tl 2013 .. did tl 
2012 work ok?

luatools is not needed; mtxrun --generate does the job (and once you 
have context installed normally this is done automatically as is format 
generation)

in the reported 'tree' files in the cache you can check if files like 
context.mkiv are present

depending on the version of texlive texmf or texmf-dist is used for files

you can run

mtxrun --variables
mtxrun --expansions

to see if there are weird settings (maybe from env vars)

so no file database is present or the database has not all files

upgrading texlive means wiping out the old one .. maybe there are traces 
of older texlives? maybe in some local texmf tree in home?

texmflocal is normally not used (afaik)

it could relate to the texmf/texmf-dist changes (although we made sure 
that we adapted the scripts etc to support that rather fundamental 
change in texlive 2013)

indeed (in the garden distribution we also have trees like texmf-context 
for context, texmf-fonts for user fonts, texmf-project for project 
specific files, while texmf-local is only used for persistent local 
overloads

does arch-linux use stock texlive or do they adapt it
