That was the ticket! I am 99% there, now. By using this:

export LDFLAGS=" -Wl,-R /home/username/progroot/lib/
-Wl,-R /home/username/progroot/usr/lib/
-Wl,-R /home/username/progroot/usr/lib/mysql/
-Wl,-R /home/username/progroot/opt/kde3/lib/
-Wl,-R /home/username/progroot/usr/lib/qt3/lib/ "

all the libs listed in "ldd program" are properly pointed to my local
libs locations. However, I still have one lib that will not get the
local subdir: /lib/ld-linux.so.2 (the dynamic loader). This lib is
in ../progroot/usr/lib/ and I don't know why it still insists on
using /lib/. On kernel 2.3.3 this results in a seg fault (compiled on
2.6.1). I guess I will probably have to look at statically linking...

Thanks for all of your help, Rainer, I really do appreciate it!
