rpmReadSignature failed: region trailer: BAD, tag 61 type 7 offset 48 count 16

This error happens when the rpms being installed are new, and the rpmbuild system trying to install those rpms is old.

One solution, instead of using the default i386 rpms, use the glibc23.i386 rpms.
They can be downloaded from the MySQL Archives

The name you'll be looking for in the list is under the "Generic Linux RPM".  The type of file is:

glibc-2.3, x86

Download all 4 of the files into a new directory:

devel: Libraries and Header files
client: Client programs
shared: Dynamic client libraries
server: Server

once all 4 are downloaded, run:

rpm -Uvh MySQL*.rpm --nodeps
