Why am I getting a “C compiler cannot create executables” (successfully written C code prior to this and compiles that)?

问题

This is the error I am getting when typing ./configure :

checking build system type... x86_64-apple-darwin11.3.0
checking host system type... x86_64-apple-darwin11.3.0
checking target system type... x86_64-apple-darwin11.3.0
checking whether the C compiler works... no
configure: error: in `/opt/ruby-1.9.3-p125':
configure: error: C compiler cannot create executables
See `config.log' for more details

As is obvious by above, I am trying to compile the Ruby source code. I did some research but doesn't look like anybody has attempted compiling the code themselves on Lion. I am currently running 10.7.3 OS X Lion, Macbook Pro.

If you have Xcode 4.3+, did you install the command-line tools? You can download them from within Xcode's preference pane, or from here.
