configure isn't finding locally installed libftdi1

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Build and install libftdi1 to /home/cmorgan/local_install
2. Run configure in libmpsse with:
./configure --prefix=/home/cmorgan/local_install CFLAGS="-I 
/home/cmorgan/local_install/include -fPIC" LDFLAGS="-L 
/home/cmorgan/local_install/lib64"
3. Output is:

checking for GNU libc compatible malloc... yes
checking libftdi1/ftdi.h usability... yes
checking libftdi1/ftdi.h presence... no
configure: WARNING: libftdi1/ftdi.h: accepted by the compiler, rejected by the 
preprocessor!

I looked in config.log:

configure:3355: gcc -c -Wall -fPIC -fno-strict-aliasing -I 
/home/cmorgan/local_install
configure:3355: $? = 0
configure:3355: result: yes
configure:3355: checking libftdi1/ftdi.h presence
configure:3355: gcc -E  conftest.c
conftest.c:21:27: fatal error: libftdi1/ftdi.h: No such file or directory
 #include <libftdi1/ftdi.h>
                           ^
compilation terminated.

I have no idea why CFLAGS isn't being used in the compile check. Is there some 
way to specify the path to libftdi1 via a configure option?

Looking at this again because of another build related thing and still can't 
figure out why the compiler isn't finding the header file. Although everything 
else looks fine. Its weird....

On OS X version 10.8.5 with a fresh libftdi1 installed from MacPorts I get 
similar issues. The library is installed by MacPorts in the (default) location 
"/opt/local" (note: is different from "/usr/local").

The following files are succesfully installed by MacPorts:
------------------------------------------
$ port contents libftdi1
------------------------------------------
  /opt/local/bin/ftdi_eeprom
  /opt/local/bin/libftdi1-config
  /opt/local/include/libftdi1/ftdi.h
  /opt/local/lib/cmake/libftdi1/LibFTDI1Config.cmake
  /opt/local/lib/cmake/libftdi1/UseLibFTDI1.cmake
  /opt/local/lib/libftdi1.2.1.0.dylib
  /opt/local/lib/libftdi1.2.dylib
  /opt/local/lib/libftdi1.a
  /opt/local/lib/libftdi1.dylib
  /opt/local/lib/pkgconfig/libftdi1.pc
  /opt/local/lib/pkgconfig/libftdipp1.pc
------------------------------------------

Surprisingly, the following ./configure trials all fail the same way:
------------------------------------------
$ ./configure
$ ./configure --prefix=/opt/local
$ ./configure --includedir=/opt/local/include

However, it does work when I use the following additional directives:
------------------------------------------
$ ./configure LDFLAGS=-L/opt/local/lib CPPFLAGS=-I/opt/local/include 
CFLAGS=-I/opt/local/include
