It turns on pathname matching, which does not use LD_LIBRARY_PATH. As a result, it fails because it cannot find "./libfoo.so". The error message matches the error of the second dlopen(), not the first's. Do not try to look for a different library ("./"-prefixed) than the one provided in argument. Let the dynamic library management handle it, just provide an appropriate LD_LIBRARY_PATH.
