Okay, then I don't know how to do that correctly. I tried, in the
ATLAS configuration script, adding -fPIC to the c-compiler flags,
which resulted, in the makefile, in:

CCFLAG0 = -fomit-frame-pointer -O3 -funroll-all-loops -fPIC

and

MMFLAGS = -fomit-frame-pointer -O -fPIC

and recompiled atlas, but still got the same error when compiling
scipy. What's the correct approach?

Thanks again,

Angus.
