Several parts of this suggest that they are "monkey boys" in the
"Buckaroo Banzai" movie sense, and unaware of how things normally
work. For example, the use of 'su -c' instead of 'sudo', the automatic
use of 'yum install' for various packages without checking for their
previous existence (which can produce unexpected and out of band
component updates), and the very, very odd creation steps for
libcrypt.so that will be overridden anytime someone updates the
'glibc-devel.i686' package.
That "ln -s /lib/libcrypto.so.0.9.8b /lib/libcrypto.so" is both
linking a system library for glibc-devel to a third party library,
which is library to break 32-bit compilation, and it's bad syntax. It
should be "ln -s libcrypto.so.0.9.8b /lib/libcrypt.so",
Overall, this is not a good installation procedure.
