The error is pretty clearly "file not found", not "no permissions".

One possibility is that the complaint is not about this file itself
but about some other shared library it depends on. Try "ldd" or
local equivalent on the file to see if it shows any unresolved
references.

Also, you might try looking in the postmaster log to see if any
additional info appears there --- anything the dynamic linker spit out
to stderr is not going to appear on your terminal.
