Parece que você ainda tem um pacote antigo do mysql 5.5 que entra em conflito com sua tentativa de instalação 5.1.
Fazendo um:
yum remove mysql-libs
deve removê-lo e permitir que você instale corretamente o seu pacote de servidor MySQL 5.1.
Não consigo instalar o MySQL 5.1 no Fedora 16. Quando tento instalar um RPM baixado do site MySQL, recebo erros de conflito com os pacotes 5.5 existentes que já removi através do yum.
TIA SO
