Hi Chris:

You might want to consider the planned USB stick distribution for PTS for
those situations where you don't have disk space for its dependencies.
However, that is just a suggestion.  I definitely don't want to
over-advocate for PTS since my knowledge of it just consists of what I have
read at phoronix, and it sounded like you had additional reservations beyond
the disk space one about PTS as well. The important goal here is to make it
possible for anyone to conveniently run benchmarks for Intel graphics. Thus,
if in your judgement that requires a non-PTS approach for whatever reason,
so be it.

jhbuild sounds like a good choice.  In the past, I have used jhbuild to
build my own version of the pango/cairo stack, and it worked well.

Fair enough.
