I'll give that a shot next...

OK - what I tried was

LD_TRACE_LOADED_OBJECTS='' \
LD_PRELOAD='/home/office/tconnors/lib/usr/lib/Linux/glibc-2.3.1/ld-linux.so.2 \
/home/office/tconnors/lib/usr/lib/Linux/glibc-2.3.1/libc.so.6' \
./mogrify

(Also switched around the things in LD_PRELOAD.)

Getting progressively closer to something resembling working, except that
it keeps trying to load /lib/ld-linux.so.2 even though it has successfully
loaded my own .../glibc-2.3.1/ld-linux.so.2

I don't suppose I can supress that - it is coded into the exectuable,
afterall...
