One thing that you should try is seeing whether the latest 0.2.4.x
release does any better for you.  In particular, I'd recommend trying
the just-released 0.2.4.16-rc, with openssl 1.0.1e, and make sure that
openssl 1.0.1e was built with the -enable-ec_nistp_64_gcc_128 option
if possible.  (I see you're already using 1.0.1e, but it doesn't
appear to have been built with that option.)

When I try to build openssl with this option on my Raspian system, I get

ecp_nistp224.c:43:3: error: unknown type name ‘__uint128_t’

It would be helpful for me to get some guidance from someone who has done this on Raspbian.
