Just to put my two yen in, one way to figure out whats going on in
cases like this is to use strace. strace traces all the system calls
that a command uses. The most useful part, is that it shows you all
the files an application is trying to open. I usually do something
like:

	strace -F -f -o out some-command

	grep open out

This will list all files, including libraries etc, that the app is
opening. 

For example:

	strace -F -f -o out ls

has the following "open" call in "out"

540  open("/etc/ld.so.preload", O_RDONLY) = -1 ENOENT (No such file or directory)
6540  open("/usr/local/lib/libc.so.6", O_RDONLY) = -1 ENOENT (No such file or directory)
6540  open("/etc/ld.so.cache", O_RDONLY) = 4
6540  open("/lib/libc.so.6", O_RDONLY)  = 4
6540  open(".", O_RDONLY)               = 4
