Hi Graham,

As far as I know, there has been no new release of TAUCS with the 
indefinite symmetric solver.  The Ipopt distribution includes some 
interface to TAUCS, contributed by Yifan Hu from Wolfram, but it used an 
inofficial release of TAUCS.  For a while, I haven't heard any updates on 

If you want to see what the status is, you might want to contact the 
developers of TAUCS, see
