OK, it was just a first guess.:-)

Hm, they should of course know more about the Erlang/OTP build than I
do, but the few words that are recognizable from the error message, like
"relocation error" and "does not fit", don't really suggest that it is
an issue with symbol resolution I think.

My next guess would be a -fpic vs -fPIC problem when compiling
crypto_drv - in many cases / architectures you can "get away" with using
-fpic which is supposedly slightly more efficient, but my understanding
is that -fPIC should always work and is sometimes required. Of course if
your build actually used -fPIC (likely), this is moot.

But then I recognized one more word from the message: "main". This kind
of contradicts what I wrote above, but surely there shouldn't be a
"main" symbol in crypto_drv. What does 'nm' say?
