Someone much smarter then me - At least in this area :-) - said....

    It is far from harmless, in fact it is HIGHLY toxic.  It isn't the
    /opt/csw/bin that it the problem but the duplicate but different
    versions of stuff from /usr/lib and other Solaris core lib
    directories it duplicates into /opt/csw/lib.  This can and will lead
    to very hard to diagnoise problems due to more of more of the
    following (plus some others): multiple different binary libs in same
    process, similar libs with partialy the same API (libldap vs
    openldap variant is one very toxic case), correct API/ABI but
    different build options for same libary, etc.

    The only correct way out of this is to rebase Blastwave for each
    operating system version so that it never duplicates libraries that
    are part of the core OS unless it does so by linking them RLTD_GROUP
    (which it doesn't). ld(1) -B group
