if ldd says you are linked against libpam.so, then you are not linked
against any specific version. you would have to take a look at
libpam.so to see which version it is. that will probably be easy
because libpam.so is generally a symlink to a more version-specific
name.
cora% ldd /lib/security/pam_unix.so | grep libpam
libpam.so.0 => /lib/libpam.so.0 (0xb7d7e000)
cora% ls -l /lib/libpam.so.0
lrwxrwxrwx 1 root root 14 2005-02-08 22:05 /lib/libpam.so.0 -> libpam.so.0.76
cora% ls -l /lib/libpam.so.0.76
-rw-r--r-- 1 root root 30360 2004-06-28 11:39 /lib/libpam.so.0.76
if you changed the libpam.so symlink to point at a different version of
libpam, then you would be linked to that other version. as mr kukuk
already alluded, that should work fine; no need to recompile or
whatever.
