[Samba] smbd crashes on Debian Lenny if using Debian's

[G.W. Haywood]

Hi there,

Installed the latest stable Samba (3.5.1) from the source tarball on a
fresh, minimal Debian Lenny server.  It took me three days to figure
out why the Samba daemon wouldn't run.  The crux of it is this:

Although I built Samba from source and it has its own version of
libwbclient, it decided to use the Debian-supplied version.  This
doesn't work with smbd for reasons that I haven't investigated.

As soon as I removed the offending libwbclient and set up the library
search path for the Samba-supplied libraries:

prompt # > echo "/usr/local/samba/lib" >>/etc/ld.so.conf.d/samba.conf
prompt # > ldconfig

the daemon started up fine.

Hoping that this might help anyone else in the same boat.

Shouldn't Samba simply use its own version by default?
