Dear Prof. Ripley,
thank you for your offer for assistance. Here are some more details from our sys admin (who sincerely thanks you for the hint to Matrix/src/taucs/taucs.h):
--- the system administrator says: ---
Since we don't have a license for the cc compiler anymore I have to use gcc. Trying to compile the Matrix package via the Makefile in Matrix/src doesn't work as this uses the cc compiler and I don't know how to change that in an appropriate way (there is no configure script for example).
As I don't really understand how R compiles downloaded packages and how and where I could change the configuration for that, I tried the following dirty hack:
- added '#define OSTYPE_solaris' in Matrix/src/taucs/taucs.h - made a new tarball (Matrix_0.8-10.tar.gz) of the directory Matrix - put PACKAGES and Matrix_0.8-10.tar.gz on my own website - installed the changed package via > options(CRAN = 'http://my_own_website...') > install.packages("Matrix")
... which did the trick. But where should OSTYPE_solaris really be set?
--- end system administrator ---
I hope these informations can shed some light onto our problem and assist you in tracking down the reason. Thanks again.
Best regards -- Gerrit Eichner

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.
