Need to install developer/assembler pkg but fails, this is needed by Oracle 11g db.

Hi guys, 

Im trying to install developer/assembler package which is one of the pre-req for install oracle 11.x db. But for some reason its failing. Error below..

root@p-erpdb:/etc# pkg install developer/assembler

Creating Plan (Solver setup): /

pkg install: No matching version of developer/assembler can be installed:

  Reject:  pkg://solaris/developer/assembler@0.5.11,5.11-0.174.0.0.0.0.0:20110921T184152Z

           pkg://solaris/developer/assembler@0.5.11,5.11-0.175.1.0.0.19.0:20120625T151738Z

  Reason:  This version is excluded by installed incorporation pkg://solaris/consolidation/sunpro/sunpro-incorporation@0.5.11,5.11-0.175.1.13.0.4.0:20131028T163450Z

It looks like the package sunpro-incorporation wants is a newer version but repository only has an older version which doesn't make sense since this is the oracle pkg site.
