"cannot open shared object file"

[Jordan Benjamin]

Hello all, 

I'm trying to use GDB with a program having many shared libraries, and I 
get the following error:

(gdb) run
Starting program: /usr/local/Amira-3.0/bin/arch-Linux-Optimize/HxMain
/usr/local/Amira-3.0/bin/arch-Linux-Optimize/HxMain: error while loading 
shared libraries: libAmira.so: cannot open shared object file: No such 
file or directory

Program exited with code 0177.

The library "libAmira.so" is found on my machine in 
/usr/local/Amira-3.0/lib/arch-Linux-Optimize/libAmira.so. I've tried 
adding /usr/local/Amira-3.0/lib/arch-Linux-Optimize/ to the shell 
variable LD_LIBRARY_PATH (which allows ldd to find it), as well as 
setting solib-search-path to this path, but to no avail. I can't even 
figure out what's generating this error message--I've grepped the gdb 
and ld source for similar wording but can't find anything. 

Do any of you have any ideas?
