[SOLVED] configure: error: C compiler cannot create executables

I've checked a number of similar questions on stackoverflow but haven't found an answer yet.

I'm trying to install memcached on Lion OSX as shown here.

Here's what I'm getting:

j-court-demones-macbook-pro:libevent-1.4.12-stable jcourtdemone$ ./configure; make
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... ./install-sh -c -d
checking for gawk... no
checking for mawk... no
checking for nawk... no
checking for awk... awk
checking whether make sets $(MAKE)... yes
checking for gcc... gcc
checking for C compiler default output file name... 
configure: error: in `/tmp/libevent-1.4.12-stable':
configure: error: C compiler cannot create executables
See `config.log' for more details.
make: *** No targets specified and no makefile found.  Stop.

I've reinstalled Xcode as was recommended in a couple places, but no dice.

Here's my config.log:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.63.  Invocation command line was

  $ ./configure
