They aren't.

This would be the culprit. Does this also happen if you repeat those
lines inside R?

Most likely.

This could be a source of problems, SuSE 5.2 is getting pretty old (6.4
is current AFAIR).  Upgrading might be the fastest way out.

Hmm. What about the built-in packages (e.g. ctest)? Did you use R
INSTALL correctly to install mclust (or install.packages('mclust'))?

In general, you need to link the shared library with the fortran libs,
either  -lg2c or -lf2c. Older compilers may not be getting this right.
