[Pythonmac-SIG] RPy and libR.dylib

[Jeff Whitaker]

Jack:  All I can say is what worked for me.  When I first tried importing
rpy with the unmodified R installation, python couldn't find libR.dylib. I
fixed that by adding the "install_name".  But then, I got undefined symbol
errors in R_X11.so - because of the "-bundle_loader" argument, dyld was
expecting them to be defined by R.  Simply removing the "bundle_loader"
produced undefined symbol errors in the R compile, so I added the
"flat_namespace" stuff and everything worked.

So, to summarize, libR.dylib and R_X11.so were initially compiled with
two-level namespaces - for me, this was the source of the problem rather
than the solution.

Gerry (or anyone else) - please let me know whether this works for you.
