 Hmm, I'm not much familiar with NetBSD (I'm here due to a general
interest in the DECstation) but that's the usual name for the the library
holding dlopen() and friends on various ELF systems.  A few have the
functions in libc, but then you wouldn't get the failure.  My apologies
for providing unverified information.

 Well, it's the CPU that is "special" to different platforms, ;-) so the
entries usually differ with the endianness setting, processor-specific
compilation options and processor-specific openssl options (a few
platforms provide hand-coded assembly functions; there are also a few
optimization choices for algorith modifications which work better or worse
depending on a CPU architecture).  Since neither of the existing entries
seem to fit NetBSD/pmax as is, I'd just copy the "NetBSD-m68" entry, since
it's the most generic, and change -DB_ENDIAN to -DL_ENDIAN.  You may want
to twiddle with the openssl optimization options as well.  I'm using
DES_PTR" for my DECstations running Linux -- you might check if they yield
better performance.
