Actually, the MAKE command should be already installed on your Mac if you have Xcode installed. But in my case MAKE have been disappeared after update from Snow Leopard to Lion OSX. By some reason PATH to MAKE was changed. So what you need to do in this case in order to make MAKE available - fix PATH e.g:
Apples-MacBook-Pro:t0-mvn apple$ make
-bash: make: command not found
Apples-MacBook-Pro:t0-mvn apple$ ls /Developer/
.DS_Store Documentation/ Icon^M SDKs/

Apples-MacBook-Pro:t0-mvn apple$ ls /Developer/usr/

bin/ include/ libexec/ local/ share/
Apples-MacBook-Pro:t0-mvn apple$ ls /Developer/usr/bin/

Apples-MacBook-Pro:t0-mvn apple$ ls /Developer/usr/bin/ma
make malloc_history mapc
Apples-MacBook-Pro:t0-mvn apple$ ls /Developer/usr/bin/make
/Developer/usr/bin/make
Apples-MacBook-Pro:t0-mvn apple$ /Developer/usr/bin/make
make: *** No targets specified and no makefile found. Stop.
Apples-MacBook-Pro:t0-mvn apple$ export PATH=$PATH:/Developer/usr/bin/
Apples-MacBook-Pro:t0-mvn apple$ make
make: *** No targets specified and no makefile found. Stop.
Then you probably will want to change your PATH variable in your profile configuration. Do this:
$ vi ~/.profile
////
export PATH=/opt/subversion/bin:$PATH:/Developer/usr/bin
