I have a new one. It seems I need to build the ATLAS libraries with -fPIC

-fPIC again...
Setting the environment flag CFLAGS=-fPIC might work. If ATLAS uses configure to setup Makefiles you will need to set this before running it again. (e.g. CFLAGS=-fPIC ./configure --prefix=/usr/local/). I have not done this with ATLAS, but this is how I solved the same problem compiling other software. cheers! Ed
