Seems Ubuntu 10.04 LTS is going to ship LLVM 2.7. I sent a request
for enabling RTTI on the package, I hope it's not too late for that:

I've put together http://llvm.org/docs/Packaging.html to document
these kinds of requests for all packagers in one place. Let me know if
any of the advice I've put there is wrong. (At the moment,
http://llvm.org/viewvc/llvm-project/llvm/trunk/docs/Packaging.html?view=co
is more up to date, but the website should catch up sooner or later.)

Looks good to me. BTW exception support for LLVM is not required
to link with code that uses exceptions. At least our toolset
seems to link fine with LLVM without this flag given for make and
it uses exceptions all over the place. So probably it's not required
to be on for the binary packages either (not sure about this).

About --enable-shared. Could it be a good compromise to allow to
link the LLVM tools statically (for the startup speedup) but still
generate also a shared lib for external projects to more easily link
with? So, by default always (additionally to the static lib) generate
the big .so but only when --link-llvm-with-shared (or similar)
is given it would link the LLVM binaries with it?
