building portmidi - c

Question

I've been tring to build portmidi on OSX 10.8.2
http://sourceforge.net/apps/trac/portmedia/wiki/Installing%20portmidi%20on%20Mac
Anyway, the README tells me to first use the command:
make -f pm_mac/Makefile.osx
but bash returns the following error message:
[~/Desktop/portmedia/portmidi]
DanMoore -> make -f pm_mac/Makefile.osx
rm -f CMakeCache.txt
mkdir -p Release
cd Release; cmake .. -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release

I wasn't expecting an easy build, but these errors look foreign to me.
Can anyone explain whats going on??
I'm trying to render a library file for simple C programs. (.a or .la)
Thanks in advance to anyone who takes a look!!
