Okay, thanks. Can I make a suggestion to the core team members, build both a FPU and non FPU version of libm and stuff it in /usr/lib. Then make libm a softlink to the emulated version. That way changing versions can be done by asking about it during install, or simply after system install... -Crh Charles Henrich Michigan State University henrich@msu.edu http://pilot.msu.edu/~henrich
