[Freeswitch-users] Building Freeswitch on OSX Lion - ./configure openssl error

I'm using the latest git commit (01267cd6f5b9a243c42c571f5d161849a66b3c82) and running into an error configuring Freeswitch on OSX Lion: ./configure: line 12283: syntax error near unexpected token `openssl,' ./configure: line 12283: ` PKG_CHECK_MODULES(openssl, openssl,' configure: error: ./configure.gnu failed for libs/iksemel ./bootstrap.sh runs fine; ./configure eventually spits out the error above. Any tips for me? I am mainly trying to set it up for local development purposes, not production. Thanks.
