No, but "sub folders inside mounts" has no meaning under unix (every  
folder on your disk is a "sub folder inside a mount").

dlopen() (which is what dynlibs calls under unix) is unrelated to  
binutils (it's part of glibc). mounts do not need resolving.  
Everything is a "mount" under unix (even the root directory).

What you can do is call dlerror when you get 0 back from loadlibrary,  
as follows:

function dlerror: pchar; cdecl; external;


if dynlibs.loadlibrary(...) = 0 then

Maybe it will tell you something more.
