I am trying to install dkim-milter-2.7.2 on a Centos 5.2 system and keep getting the following errors.

I have very little experience in C programing so I am at a loss as how to proceed. I have sendmail-devel installed

Here is the tail of the result output of

sh ./Build

make[2]: cc: Command not found make[2]: *** [assert.o] Error 127 make[2]: Leaving directory `/etc/mail/dkim/dkim-milter-2.7.2/obj.Linux.2.6.18-92.1.22.el5xen.i686/libsm' make[1]: *** [/etc/mail/dkim/dkim-milter-2.7.2/obj.Linux.2.6.18-92.1.22.el5xen.i686/libsm/libsm.a] Error 2 make[1]: Leaving directory `/etc/mail/dkim/dkim-milter-2.7.2/obj.Linux.2.6.18-92.1.22.el5xen.i686/dkim-filter' make: *** [all] Error 2

Any ideas?
