Well, the setup.bin probably got deleted when the error happened...but that's not important.
Check your /etc/ld.so.conf file, look at the paths listed there... Make sure it has at least these:
/lib
/usr/lib
/usr/local/lib
Run ldconfig as root and try again.
Then again, since you're using Mandrake, you can always
search for RPMs which are much easier to install.
