Hi Stephen:

Thanks for your reply.

#export MAKE_JOBS_UNSAFE=yes
made some of the seemingly random errors go away when i was building 'octave' 
from the ports.

Yes, reading a couple of threads on the toolchain list seems to suggest some 
kind of incompatibility and linker issue.

Hence my approach is:

1. checkout the latest '/usr/src' tree. (done)
2. make buildworld (wip)
3. make buildkernel
4. make installkernel
5. reboot
6. make installworld
7. reboot
8. cd /usr/ports/math/sage
9. make

Guess i will learn a thing or two :) will keep you posted of how the build goes

thanks
Saifi.
