I tried the same on a newer, upgraded 'squeeze' system and got the same
problem:

In 1.5.0, I am finding that various modules cannot see symbols in the core:

'wav' is not the only one with this problem:

Now, these symbols are in fact quite there:
diminuendo-1:~/sems-1.5.0/core# nm /usr/local/sbin/sems | grep
_ZN9AmSession3runEv
080f6620 T _ZN9AmSession3runEv
diminuendo-1:~/sems-1.5.0/core# nm /usr/local/sbin/sems | grep
run_log_hooks
081363d0 T run_log_hooks
And as far as I know, libdl is fine on this system. Is there any reason
why RTLD_LAZY | RTLD_GLOBAL might suddenly not work?
Admittedly, this is an older Debian 'testing' system, and I have not
tried reproducing on a somewhat more updated system.
