Description:
There is a small bug in the samba PKGBUILD which causes smbclient to depend on tdb>=$pkgver instead of tdb>=3.4.3.

This line (there are two of them)
depends=('readline>=6.0.00' 'popt' 'libldap>=2.4.18-1' 'libcap>=2.16' 'heimdal>=1.2-1' 'db>=4.7' 'tdb>=$pkgver')

should be replaced with
depends=('readline>=6.0.00' 'popt' 'libldap>=2.4.18-1' 'libcap>=2.16' 'heimdal>=1.2-1' 'db>=4.7' "tdb>=$pkgver")
