OK - my error on libraries moving out into -dev - they where actually in
/lib32 (see output from maverick system below)

jamespage@hendrix:~/src/natty/jna/libjna-java-multiarch-fix/src/com/sun/jna$ ldconfig -p | grep libpam.so
	libpam.so.0 (libc6,x86-64) => /lib/libpam.so.0
	libpam.so.0 (libc6) => /lib32/libpam.so.0
	libpam.so (libc6) => /lib32/libpam.so
jamespage@hendrix:~/src/natty/jna/libjna-java-multiarch-fix/src/com/sun/jna$ 

So dlopen('libpam.so') did work before - but only because libpam.so was
in ld.so.cache courtesy of ia32-libs.

I've made a few further comments in the linked merge proposal with
regards to JNA behaviour

Title:
  JNI unable to find libpam.so

Status in “libjna-java” package in Ubuntu:
  Triaged
Status in “openjdk-6” package in Ubuntu:

Bug description:
  I'm currently packaging Jenkins for Ubuntu; this application has
  native authentication integration through the use of PAM. This was
  working fine i.e. the java native interface dispatcher was able to
  find libpam.so in /lib and all was happy.

  I've just updated my test system and native authentication no longer
  works; the JNI dispatcher can't find the library.  I have done a bit
  of digging and it looks like libpam.so.* is installed to /lib/i386
  -linux-gnu instead of /lib (as on Maverick and possibly earlier Natty
  releases?).  This directory is not on the java.library.path by default
  which I suspect may be the issue (see below for default java library
  path):

  /usr/lib/jvm/java-6-openjdk/jre/lib/i386/client:/usr/lib/jvm/java-6-openjdk/jre/lib/i386:/usr/lib/jvm/java-6-openjdk/jre/../lib/i386:/usr/java/packages/lib/i386:/usr/lib/jni:/lib:/usr/lib

  So I'm not sure whether this is a bug in pam or openjdk but I guess it
  could be either.
