PostgreSQL version: 9.1.3
Operating system:   Mac OS X 10.7.4
Description:=20=20=20=20=20=20=20=20

running configure as such:

export MACOSX_DEPLOYMENT_TARGET=3D10.7
export CC=3Dgcc
export CPP=3D"gcc -E"
export CXX=3Dg++
export CXXFLAGS=3D'-O3 -fno-common -arch x86_64'
export CFLAGS=3D'-O3 -fno-common -arch x86_64'
export LDFLAGS=3D'-O3 -fno-common -arch x86_64'

./configure  \
  --prefix=3D/usr/local \
  --enable-integer-datetimes \
  --enable-thread-safety        \
  --with-libxml         \
  --with-libxslt        \
  --with-ossp-uuid      \

  --with-ldap             \
  --with-bonjour          \
  --with-openssl       \
  --with-zlib

During the configuration phase, I get this message:
