rgl revisions to allow dual install

Duncan,
I see now. On PPC you should use

    file.exists(system.file("libs/ppc", "aglrgl.so", package ="rgl"))

and, under intel,

    file.exists(system.file("libs/i386", "aglrgl.so", package ="rgl"))

instead of just

    file.exists(system.file("libs", "aglrgl.so", package ="rgl"))

i.e.
    file.exists(system.file(file.path("libs",.Platform$r_arch),
"aglrgl.so", package ="rgl"))

And yes, you have to explicitly set the DISPLAY var under the shell  
unless you use xterm.

I have only one doubt, which I'm going to verify: if you override the
DYLD_LIBRARY_PATH var there should be potential problems with tcltk
which is still x11.

It builds fine on PCC and apparently the two libs are in the

The only problem is that both on X11 term and on R.app always the
X11 .dll is taken, so no AGL for me any more.
I don't see any conditionals on .Platform$GUI in the loading of the
library though.

It's in the .onLoad function in zzz.R:

   if ( .Platform$OS.type == "unix" ) {
     unixos <- system("uname",intern=TRUE)
     if ( unixos == "Darwin" ) {
       # For MacOS X we have to remove /usr/X11R6/lib from the
DYLD_LIBRARY_PATH
       # because it would override Apple's OpenGL framework

Sys.putenv("DYLD_LIBRARY_PATH"=gsub("/usr/X11R6/lib","",Sys.getenv
("DYLD_LIBRARY_PATH")))
       if ( .Platform$GUI == "AQUA" &&
            file.exists(system.file("libs", "aglrgl.so", package =
"rgl"))) {
         initValue <- 1
         rgl <<- "aglrgl"
       }
     }
   }

Does the lib get a different name or sit somewhere else on that
system?
  I have the file.exists test in case someone has configured not to
build the AGL version, but maybe the filename is wrong.  Do you  
know a
safe test to see if the lib exists?

and, for the standard  shell (i.e. not under xterm), I can open and

rgl.open()

Error in rgl.open() : rgl.open failed

rgl.open

The initialization is currently done in .onLoad, and if it fails, no
additional attempts are made.  I'll see if it's safe to try again.

By the way, did you manually set DISPLAY before you opened the x11
device?  I get an error in the standard shell when I try that, but
Sys.putenv fixes it.
