Ah, thanks. I did in fact discover the following 64-bit libraries were
installed into /usr/lib instead of /usr/lib64:

1. From DAHDI, libtonezone.so

2. From LibPRI, libpri.so

3. From Asterisk, libasteriskssl.so

I found that running "ldconfig" caused them all to be discovered:

So I assumed that all should be ok, otherwise the executables would fail to run
(I initially discovered this when dahdi_cfg couldn't find libtonezone).

Would there be any subtle issues with the 64-bit libraries being loaded
from /usr/lib instead of /usr/lib64?

Should Asterisk and DAHDI builds also be updated to use /usr/lib64 when
building on a 64-bit OS? Or the build instructions?
