If you want you can try one of these:
  http://mirror.opencsw.org/opencsw/allpkgs/alternatives-1.3.30c%2cREV%3d2010.02.18-SunOS5.8-i386-CSW.pkg.gz
  http://mirror.opencsw.org/opencsw/allpkgs/alternatives-1.3.30c%2cREV%3d2010.02.18-SunOS5.8-sparc-CSW.pkg.gz

They should work correctly on the provided packages even when in one file.


Best regards
