Check dmesg and/or /var/log/messages.  Quite often "No such file or
directory" means that the kernel returned ENOENT.  This typically
happens due to a failure in the in-kernel linker due to a symbol
not being found in the kernel that the module requires.  dmesg will
show any kernel linker message and help you debug the issue.
