[pca] Connecting different, non-obsolete patches

We talked about that here a few days before you subscribed. See the 
thread in the archive at:

   http://www.mail-archive.com/pca@lists.univie.ac.at/msg01446.html

It also points at a script of mine (chkmin), available from:

   http://www.par.univie.ac.at/solaris/pca/contrib.html

You can feed a list of patches to it (e.g. the prerequisite patches for 
LU) and it will reduce the list to those which are missing.

I think you misunderstood how the kernel patches are organized - they 
build on top of each other, so if you want to install 139555-08, you 
will have to install all the others, too.
