Sorry you haven't gotten a quicker response here. I'm not particularly familiar with your distribution, but . . . maybe I can offer some general guidance. It's always helpful if you can provide the versions of everything you are referencing. Are you trying to build the latest Amanda?
Is there a particular reason you aren't using `yum install glibc`? I saw some comments on the
CentOS forum that installing a different version of glibc from what the distribution is based on could cause stability problems.
Also, you can get packages for Amanda at
http://www.zmanda.com/download-amanda.php. The rhel5 package should work for Centos 5.5. That should make the whole process of installing Amanda and getting your server up and running much easier.
