I tried using Carlo's configure options

	http://www.nabble.com/Re%3A-Latest-from-hg-on-OSX-p17932976.html

I modified his prefix to reflect Finks. Specificlally

./configure LDFLAGS="-L/sw/lib -framework OpenGL" CPPFLAGS="-I/sw/ 
include -FOpenGL" F77=gfortran FFLAGS="-ff2c" --prefix=/sw

As before, the summary form configure came up empty for the OpenGL  
Library. However, in this instance the  BLAS Library also came up  
empty and was accompanied by the same warning (respecting BLAS) at the  
end of the configure process. That the BLAS Library came up empty it  
to be expected (I think) since the no configure options pointed to a  
BLAS Library (correct?).

Regarding the back end ...

   gnuplot:              gnuplot
   OPENGL libraries:
   fltk backend libs:    -L/sw/lib -L/usr/X11R6/lib -framework OpenGL - 
dylib_file /System/Library/Frameworks/OpenGL.framework/Versions/A/ 
Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/ 
Versions/A/Libraries/libGL.dylib -lfltk_gl -lGLU -lGL -lfltk -lXft - 
lpthread -lXext -lX11

As Jaroslav suggested I also tried removing the "-ff2c" option.  
However, the BLAS warning remains.

Regarding BLAS, I'm using gfortran 4.3, but Apple's vecLib is built  
with gcc 4.0. This resulted in some problems in the past. If I recall  
correctly the manner in which values of complex functions returned  
their values changed in gfortran 4.1 (?).

Using Fink's ATLAS (which depends upon gcc 4.3),  instead of Apple's  
vecLib, the configure process does find the intended BLAS ...

   Fortran libraries:    /sw/lib/gcc4.3/lib/libgfortran.dylib
   BLAS libraries:       /sw/lib/liblapack.dylib

... but still issues the same warning as before :-(

My original question was with regards to the OpenGL/backend part.  
After mergine Carlo's and Fink's configure options, I get

   gnuplot:              gnuplot
   OPENGL libraries:
   fltk backend libs:    -L/sw/lib -L/usr/X11R6/lib -framework OpenGL - 
dylib_file /System/Library/Frameworks/OpenGL.framework/Versions/A/ 
Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/ 
Versions/A/Libraries/libGL.dylib -lfltk_gl -lGLU -lGL -lfltk -lXft - 
lpthread -lXext -lX11

It appears to me that there is a problem with OpenGL. Can some one  
confirm? Am I missing a configure option specific to OpenGL? Below are  
the options I used without the BLAS part.

./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  
LDFLAGS="-L/sw/lib -framework OpenGL" CPPFLAGS="-I/sw/include - 
FOpenGL" FFLAGS="-ff2c"

Regarding BLAS, it appears that I get the same result using Apple's  
vecLib, Fink's ATLAS package, and that included in Octave. Are any  
other OSX users seeing this?
