the samba.spec file is out of date 

Missing references to mount.cifs and umount.cifs.

 gcc -o mount.cifs -O2 -g -D_GNU_SOURCE -Wall -D_GNU_SOURCE -D_LARGEFILE64_SOURCE mount.cifs.c
/tmp/ccpTpDGR.o: In function `main':
/usr/src/redhat/BUILD/samba-3.0.35/source/client/mount.cifs.c:1404: undefined reference to `unlock_mtab'

collect2: ld returned 1 exit status
error: Bad exit status from /var/tmp/rpm-tmp.36860 (%build)



I modified the spec file to not build these 2 items anymore.
Afterwards i got errors related to cifs.upcall. Is this a new component that needs to be added?

here's a patch that I used to fix the problems that I encountered.
