[pca] Missing packages while installing patches

[Martin Paul]

Hi Josep,

Yes. pca (actually patchadd, which is used by pca to install patches) 
installs patches when at least one of the packages included in a patch 
is installed.

The above situation is quite common, BTW. SUNWsmbaS contains the source 
for samba, which is not installed by default. The patch includes 
modifications both to the binaries and sources. As you don't have the 
sources installed, they don't need to be updated.

This leads to one of the problems with Sun's packacke/patch system. If 
you have package A installed, then install patch 1 with fixes for 
packages A and B, the fixes for A will be applied. If you later install 
package B, you will have to re-install patch 1 to ensure that the fixes 
from the patch are applied to package B as well.

Hope that helps,

Martin.
