To pick up this thread again,

I've installed rgl from source and overall it works fine except that
during the demo, I get a message first, at the regression demo 
as below: 

RGL: Pixmap load: file format unsupported
RGL: Pixmap load: failed

I traced the error to the command:
RGL: Pixmap load: file format unsupported
RGL: Pixmap load: failed

and further to the argument 

I have the png libraries and the png demos work.  

    jpeg      png    tcltk      X11    GNOME     libz http/ftp  sockets 
    TRUE     TRUE     TRUE     TRUE    FALSE     TRUE     TRUE     TRUE 
  libxml     fifo   cledit  IEEE754    bzip2     PCRE 
    TRUE     TRUE     TRUE     TRUE     TRUE     TRUE 
if that information is accurate.

The only thing that I've been able to spot further is in the 
compilation during installation:

g++ -no-cpp-precomp -I/Library/Frameworks/R.framework/Resources/include -I/
System/Library/Frameworks/OpenGL.framework/Headers  -I -DHAVE_PNG_H  -DDarwin 
-DNO_GL_PREFIX -I/usr/X11R6/include -I/usr/local/include  -Wall -pedantic 
-fno-exceptions -fno-rtti -fno-common  -g -O2 -c scene.cpp -o scene.o
scene.cpp: In member function `void Texture::beginUse(RenderContext*)':
scene.cpp:1994: warning: invalid conversion from `int*' to `GLint*'

I reported this to the maintainer a few weeks ago, with no response
yet.  Seeing the discussion on the help page, I thought that someone
might have a better idea.

I'm using Mac 0SX 10.3.8

platform powerpc-apple-darwin6.8
arch     powerpc                
os       darwin6.8
