The problem stems from my not understanding the configuration of the 
taucs package, which I have included in the Matrix package for one 
routine only.  I configured the taucs package on a Linux machine then 
copied it into Matrix/src/taucs/.

Rather than redoing the taucs package so that it works properly I will 
probably use the LDL' form of the Cholesky decomposition from Tim 
Davis's LDL package and remove taucs entirely.

Watch for a new upload of the Matrix package in the next two days.
