While I can get "mthca.a" to link statically, I get warnings
and the binary doesn't work.

Sounds like libibverbs *must* dynamically load mthca.so in order to operate.
I'll look at libibverbs source but this smells like a rat hole.
I'm also wondering why "-dn" and "-Bstatic" do NOT produce static binary.
"man ld" suggests those are equivalents to "-static".
thanks,
