[Koha] yaz failed dependencies on CentOS 5

hi, I'm the sysadmin from a University in Mexico and I've been trying to install Koha for our library. When I used fedora 5 some years ago it installed fine but now we are using Centos 5 and I cant install ZOOM nor yaz properly. I've tried to rebuild the src rpms for yaz and then compiling ZOOM perl bindings from source and it seems ok but then the Koha perl installer keeps saying that zoom is not installed. -- Dr. Mat.
