If ladspa-devel isn't found you need to install the epel repo for CentOS

rpm -ivh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm
sudo yum -y install ladspa-devel
cd /usr/src
wget http://web.mit.edu/tbaran/www/autotalent-0.2.tar.gz
wget ftp://ftp.pbone.net/mirror/www-ccrma.stanford.edu/planetccrma/mirror/centos/linux/planetccrma/5/x86_64/ladspa-tap-plugins-0.7.0-5.el5.ccrma.x86_64.rpm
wget ftp://ftp.pbone.net/mirror/atrpms.net/sl5-x86_64/atrpms/stable/libgsm1-1.0.13-2.el5.x86_64.rpm
wget ftp://ftp.pbone.net/mirror/download.fedora.redhat.com/pub/fedora/epel/5/x86_64/fftw3-3.2.2-3.el5.x86_64.rpm
wget ftp://ftp.pbone.net/mirror/www-ccrma.stanford.edu/planetccrma/mirror/centos/linux/planetccrma/5/x86_64/ladspa-swh-plugins-0.4.15-11.el5.ccrma.x86_64.rpm
rpm -ivh ladspa-tap-plugins-0.7.0-5.el5.ccrma.x86_64.rpm
