If you don't have this file you can download last version
of Samba on www.samba.org and do:

\$ tar zxvf samba-2.2.x.tar.gz
\$ cd samba-2.2.x/source
\$ ./configure
\$ make bin/libsmbclient.so

Then you can find libsmbclient.h in source/include directory and
libsmbclient.so in source/bin directory. You can then put them in
/usr/include and /usr/lib (or /usr/local/include and 
/usr/local/lib)
