Sure (once I unwind my shell-code).
    bin/pca --install missing --xrefdir=patchdiag.xref.d/latest --nocheckxref  \

With 'etc/pca_ignore.conf' consisting of:
  ignore=137294

Ah, my apologies here, my diff-explanation wasn't very clear.  It appears
that an entry in the pkginfo has changed between 124867-14 and -15:
  124867-14:
    SUNW_REQUIRES=124861-07 126495-03
  124867-15:
    SUNW_REQUIRES='124861-07 126495-03'
which does seem to match up with the error message.
  0 For patch 124867-15, required patch '124861-07 does not exist.

As a side-note, the actual dependency was already on the system:
  hebe> showrev -p | grep '^Patch: 124861'
  Patch: 124861-02 Obsoletes:  Requires:  Incompatibles:  Packages: SPROlang, SPROlangx
  Patch: 124861-15 Obsoletes:  Requires:  Incompatibles:  Packages: SPROlang, SPROsunms, SPROmrcom, SPROlangx

Yeah, after digging around in the patchdiag.xref a bit more, I realised that
that 'previous patch' information wasn't there.
