I did a quick test and adding unixODBC-devel did nothing to my
platform file on both Intel and AMD, so maybe it had a problem
in the past and now it has become an urban legend.
Maybe some other third party repo package mangled it. The OP's
yum log should show what packages were installed when, so just
need to trace it back to when it stopped working and look at
what packages were installed and from where and test them
out.
