Hi again, Duncan,
One more piece of information that seems relevant. I said that
it rgl compiled by which I meant that it got to the end of
the compilation and left an rgl package in my library directory,
but looking back through the compilation, I found the following
error which does seem to be pertinent, if that might help...
mkdir -p AGL
mv AGL/* .
MAKINGAGL=TRUE /Library/Frameworks/R.framework/Resources/bin/R CMD
SHLIB -o aglrgl.so *.cpp *.c
mv: rename AGL/* to ./*: No such file or directory
make: [aglrgl.so] Error 1 (ignored)
That's not a problem -- the build script builds 2 versions of some
files, and the first time through they don't exist, so you get that
error, which is ignored.
The problem is with the Freetype library, which is being detected at
build time but which is not available at run time. All I can say is
that it works for me, I don't know why it doesn't work for you. (I'm on
OS X 10.4.11, you're probably on 10.5?) You can try to configure rgl
without Freetype by using --disable-ftgl as a configure option, i.e.
R CMD INSTALL --configure-args=--disable-ftgl ...
but I don't know how to get it to work.
I've copied this to R-sig-mac; maybe someone there can suggest a fix.

Thank you.
best,
Ken

Hi Duncan,
I was able to install rgl with no problems from source
on R 2.8 but get an error when I try to load it:
library(rgl)
Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared library

Here is some further information:

attached base packages:

Any ideas? Please don't slay the messenger. Hope that all is well
otherwise.
Thanks.

Ken
