Install the "make" package. You man also need autoconf, automake, and binutils. Autoconf and automake are what create the kind of package that you are trying to install (that has a "configure" script which generates a Makefile). Binutils contains programs like ld. You probably already have the binutils package package installed.
By the way, download the mplayer package source under your home directory where you have full permissions, and run "./configure <options>" and "make" as a regular user. Only run "make install" as root.
You may need to delete the mplayer-<version>/ directory and re-untar the package, since some of the object files created are now owned by root.
