I know it's an old thread, but I got into this once again with Oracle 12c and LD_LIBRARY_PATH has been set correctly. I have used strace to see what exactly it was looking for and why it failed:

 strace sqlplus /nolog

sqlplus tries to load this lib from different dirs, some didn't exist in my install. Then it tried the one I already had on my LD_LIBRARY_PATH:

open("/oracle/product/12.1.0/db_1/lib/libsqlplus.so", O_RDONLY) = -1 EACCES (Permission denied)

So in my case the lib had 740 permissions, and since my user wasn't an owner or didn't have oracle group assigned I couldn't read it. So simple chmod +r helped.
