You simply need to install make!
RHEL-based:
yum install make
Debian-based
apt-get install make
I had the same problem after upgrading to OS X Lion. I updated X Code to 4.1 and everything was better!
I had the same problems after a Time Machine update. Installing Xcode and the along coming developer tools fixed that issue.
FYI, you need to run the "Install Xcode" app if you downloaded it from the Appstore on a Lion in order to finish the install. Seems silly, but I missed it.
Same issue aftering updating to Mountain Lion. You need to get the new command line tools and run:
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
Src: Upgrading to Mountain Lion and XCode 4 broke my "make"?
If after this you still get an error like this:
make: /usr/bin/gcc-4.2: No such file or directory
A symlink will sort out that issue:
sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
As one of the comments on this post states.
It might not be the best solution but it works, there's surely something else to it.
If you have Mountain Lion and XCODE 4.4.1 you have to go here https://developer.apple.com/downloads/index.action and download the command line tool (it's free so you don't have to pay for iOS or MAC developer program) to download this tool.
It works for me.
