I've started a fresh build and am now past liboctave and libcruft.

I can think two things that may be different (besides that I'm running  
10.5.6).

(1) I'm using Thomas' macro to make sure the OpenGL stuff is found.

If you're not using it, give it a try. If you are, make sure you're  
not passing some OpenGL specifics to configure.

When running configure I pass the following options ...

./configure --prefix=/sw FLIBS=/sw/lib/gcc4.3/lib/libgfortran.dylib  
F77=/sw/bin/gfortran --infodir='${prefix}/share/info' --mandir='$ 
{prefix}/share/man' --libexecdir='${prefix}/lib' -enable-shared - 
enable-dl --disable-static --without-mpi --with-hdf5 --with-fftw  
CPPFLAGS="-g -I/sw/include -I/sw/include/freetype2" FFLAGS="-g -ff2c"  
LDFLAGS="-L/sw/lib/fltk-aqua/lib -L/sw/lib -lfltk_gl -lfltk -lpthread"  
$blas

where $blas points to vecLib and is defined as

blas='--with-lapack=-Wl,-framework,Accelerate,-dylib_file,/System/ 
Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/ 
vecLib.framework/Versions/A/libLAPACK.dylib:/System/Library/Frameworks/ 
Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/ 
libLAPACK.dylib --with-blas=-Wl,-framework,Accelerate,-dylib_file,/ 
System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/ 
vecLib.framework/Versions/A/libBLAS.dylib:/System/Library/Frameworks/ 
Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/ 
libBLAS.dylib'

Also notice I've setup things to work with the Fink package manager.

(2) I've also modified the tests for FTGL in configure.in

  707 #ifdef HAVE_FTGL_FTGL_H
  708 #ifdef HAVE_FTGL_UPPERCASE
  709 #include <FTGL/FTGL.h>
  710 #include <FTGL/FTGLTextureFont.h>
  711 #else
  712 #include <FTGL/ftgl.h>
  713 #include <FTGL/FTGLTextureFont.h>
  714 #endif
  715 #elif HAVE_FTGL_H
  716 #ifdef HAVE_FTGL_UPPERCASE
  717 #include <FTGL.h>
  718 #include <FTGLTextureFont.h>
  719 #else
  720 #include <ftgl.h>
  721 #include <FTGLTextureFont.h>
  722 #endif
  723 #endif], [
