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.
