[pca] 124867-15 fails dependency check

[Martin Paul]

Hi David,

Can you show the complete pca command (and possible "ignore" settings in 
pca configuration files) you used which caused the error?

That's fine, actually. The patchdiag.xref file lists the same 
dependencies for 124867-15:

   124867|15|Aug/04/10| | | |  |Unbundled|sparc;124861-07;126495-03;|...

So pca should have tried to install 124861 first, if it's missing from 
your system. It definitely sees the dependency:

   $ pca -H -l 124867
   124861 -- < 19 --- 130 Sun Studio 12: Compiler Common patch ...
   126495 -- < 04 --- 361 Sun Studio 12: Patch for debuginfo handling
   124867 -- < 15 ---   2 Sun Studio 12: Patch for C 5.9 compiler

I know what you're after, but unfortunately it doesn't work like that. 
As the xref file contains no information about old patch revisions, it 
doesn't know what patch preceded 124867-15. It could be 124867-14, but 
also e.g. 124867-13 (revisions are skipped sometimes) or a completely 
different patch ID (sometimes a revision which is not 01 is the first 
one of a patch to be published).

Martin.
