[CentOS] re-install package

I tried to install alsa 1.0.19 on centos 5.3 64 - did not work - compile 
errors.

I need to re-install alsa-lib and alsa-util .
I dont want to do rpm -e first on those packages as dependcy is crazy.
I know they were installed (rpm -qa | grep alsa tells me so) I just want 
to re-install ?
How do I do that?

Thanks,

Jerry
