>Description:


when attempting to delete several packages when one depends on another, the 
package depended on can't be deleted. This seems to be independent on the 
ordering of package names on command line.


>How-To-Repeat:


(nas depends on p5-perl-headers)
pavel@pc:~$ pkg_delete -n p5-perl-headers-2.0_BETA nas
pkg_delete: package `p5-perl-headers-2.0_BETA' is required by other packages:
        nas-1.6nb3
Would execute de-install script at this point (arg: DEINSTALL).
Attempting to delete package `nas-1.6nb3'
Attempting to remove dependency on package `p5-perl-headers-2.0_BETA'
Would execute post-de-install script at this point (arg: POST-DEINSTALL).
pkg_delete: 1 package deletion(s) failed

pavel@pc:~$ pkg_delete -n nas p5-perl-headers-2.0_BETA 
pkg_delete: package `p5-perl-headers-2.0_BETA' is required by other packages:
        nas-1.6nb3
Would execute de-install script at this point (arg: DEINSTALL).
