New description:

 This came up while installing an R package that uses the OpenMP framework.
 The package requires autoconf to be installed. Clean install of MacPorts
 with only autoconf with XCode V5.0.1 on OS X 10.8

 Works expected with `./configure` with OpenMP support.

 Install the llvm-gcc42 port and configure fails with

 {{{
 checking for llvm-gcc-4.2 -arch x86_64 -std=gnu99 option to accept ISO
 C89... none needed
 checking for llvm-gcc-4.2 -arch x86_64 -std=gnu99 option to support
 OpenMP... unsupported
 configure: WARNING: OpenMP does NOT appear to be supported on this system.
 configure: creating ./config.status
 }}}

 The log file indicates:
 {{{
 configure:2614: llvm-gcc-4.2 -arch x86_64 -std=gnu99 -o conftest
 -mtune=core2 -g -O2   conftest.c  >&5

 I've attached the config.log file.
