I guess, the main reason for the problems is inconsistent usage of `-Wl,-rpath,somedir' vs. LD_RUN_PATH; AFAIK, `-Wl,-rpath,...' disables LD_RUN_PATH at linktime and LD_LIBRARY_PATH at runtime. I don't know, which way libtool is using, but I tend to strongly recommend against using -Wl,-rpath.

Using -rpath will indeed cause the linker to ignore LD_RUN_PATH (at least, that is how the GNU linker behaves). However, it does not cause the dynamic linker to ignore LD_LIBRARY_PATH when the executable is run. Ian
