Probable shared library conflict.

This is useful, now the question is what libraries do PAM and/or the
system nsswitch bring in?

Do not think there is such an equivalent for FreeBSD looking over my nsswitch on my ferdora box i am not sure where i would find this on BSD
/loader/boot mabey i don't really know.

 Please post the contents of /etc/nsswitch.conf
(or FreeBSD equivalent). It may be the case that nsswitch or PAM loads
an incompatible Berkeley DB

now that u mention it there were two verions of berkeley db on my system i removed one and then reinsalled the other that postfix was depending on and got this during reinstall. Of course postfix is still broken.

Libraries have been installed in:
   /usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Multiple incompatible implementations of the same interface within
the same address-space are a problem on all systems. The degree of
the damage varies, but the problem is never removed so long as dynamic
loading is employed. My $0.02 is that all use of dynamic loading are
design failures that are correctly addressed via IPC.
